How does a circuit work?
A circuit works through a series of components mainly resistors, capacitors, and IC's. There are different types of IC's the main groups are AND, OR, NOR, & NAND. Those are just the basics you first learn about when dealing with electronics. These IC's work from what we call the binary code which is just a bunch of 1's and 0's. 1 is a logical high which gives you a positive voltage and 0 is a logical low which gives you no voltage. Lets say you have an and gate hooked up to a 150ohm resistor(it's used for voltage protection of your component)connected to a simple LED. In order to get this LED to have a logical high both inputs A and B have to get a high in order for your output to be high which in return allows voltage to pass through the resistor to your LED this powering your light emmitting diode. i hope this helped.
A circuit is just that a circuit of something. In electricity, it is the flow of electricity from the power source, through the wires, and back to the power source. You flip a switch, the power flows to the device, and continues back completing the circuit.

Current flow The answer you are looking for is Amperes or Amps. They are used to measure current flow and Amps do the actual work as they move electrons throughout the system.…
An electrical circuit is any closed loop that allows a flow of electrons in a current to deliver energy or perform work and then return to their source. Material… along which electrical current flows freely are called conductors. (e.g. copper-wire) The electrons emit and return to an energy supply. Current is said to flow from positive to negative, because this is the conventional direction of current flow. It is a convention leftover from the when electricity was first discovered. Electrons actually move through a conductor away from the negative terminal and towards the positive terminal, because of the laws governing electric fields (like charges repel and unlike charges attract). The power-supply produces an EMF (electro-motive-force) that ctreates the potential difference necessary for electrons to flow freely along a conductor. The natural force is called Electromagnetism. Opposite charges attract. An electron will move away from a negative terminal and towards the positive. In physics it is best to think of the current flow in a metallic conductor as being the overall net flow of negative charge since that is what carries energy This movement is known as net current drift and is slow compared to continual random motion of electrons. That random motion yields no overall displacement over time. Therefore power is neither consumed nor created along a current. Only in the power supply (nee. "Battery"). ****Irrelevant prose removed; ****Questions removed in answer; ****Data unrelated to question found in answer removed; ****Out-of-date Web-data removed; ****Stated "Opinions" removed. -ed
An electrical circuit must be complete i.e it must form a closed loop,for it to work. Current only flow if the circuit is complete. A complete circuit is one that consist of a… Voltage source, a consumer like a bulb and conductors. The conductor then connects the consumer and the voltage source together forming a closed loop.

The circuit breaker is an absolutely essential device in the modern world, and one of the most important safety mechanisms in your home. Whenever electrical wiring in a buildi…ng has too much current flowing through it, these simple machines cut the power until somebody can fix the problem. Without circuit breakers (or the alternative, fuses), household electricity would be impractical because of the potential for fires and other mayhem resulting from simple wiring problems and equipment failures. In this article, we'll find out how circuit breakers and fuses monitor electrical current and how they cut off the power when current levels get too high. As we'll see, the circuit breaker is an incredibly simple solution to a potentially deadly problem. To understand circuit breakers, it helps to know how household electricity works. Electricity is defined by three major attributes:VoltageCurrentResistance Voltage is the "pressure" that makes an electric charge move. Current is the charge's "flow" -- the rate at which the charge moves through the conductor, measured at any particular point. The conductor offers a certain amount of resistance to this flow, which varies depending on the conductor's composition and size. Voltage, current and resistance are all interrelated -- you can't change one without changing another. Current is equal to voltage divided by resistance (commonly written as I = v / r). This makes intuitive sense: If you increase the pressure working on electric charge or decrease the resistance, more charge will flow. If you decrease pressure or increase resistance, less charge will flow. To learn more, check out How Electricity Works. Circuit Breaker: At Work in Your HomeThe power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral wire, leads to ground. Because the hot wire connects to a high energy source, and the neutral wire connects to an electrically neutral source (the earth), there is a voltage across the circuit -- charge moves whenever the circuit is closed. The current is said to be alternating current, because it rapidly changes direction. (See How Power Distribution Grids Work for more information.) The power distribution grid delivers electricity at a consistent voltage (120 and 240 volts in the United States), but resistance (and therefore current) varies in a house. All of the different light bulbs and electrical appliances offer a certain amount of resistance, also described as the load. This resistance is what makes the appliance work. A light bulb, for example, has a filament inside that is very resistant to flowing charge. The charge has to work hard to move along, which heats up the filament, causing it to glow. In building wiring, the hot wire and the neutral wire never touch directly. The charge running through the circuit always passes through an appliance, which acts as a resistor. In this way, the electrical resistance in appliances limits how much charge can flow through a circuit (with a constant voltage and a constant resistance, the current must also be constant). Appliances are designed to keep current at a relatively low level for safety purposes. Too much charge flowing through a circuit at a particular time would heat the appliance's wires and the building's wiring to unsafe levels, possibly causing a fire. This keeps the electrical system running smoothly most of the time. But occasionally, something will connect the hot wire directly to the neutral wire or something else leading to ground. For example, a fan motor might overheat and melt, fusing the hot and neutral wires together. Or someone might drive a nail into the wall, accidentally puncturing one of the power lines. When the hot wire is connected directly to ground, there is minimal resistance in the circuit, so the voltage pushes a huge amount of charge through the wire. If this continues, the wires can overheat and start a fire. The circuit breaker's job is to cut off the circuit whenever the current jumps above a safe level. In the following sections, we'll find out how it does this. Breaker Design: BasicThe simplest circuit protection device is the fuse. A fuse is just a thin wire, enclosed in a casing, that plugs into the circuit. When a circuit is closed, all charge flows through the fuse wire -- the fuse experiences the same current as any other point along the circuit. The fuse is designed to disintegrate when it heats up above a certain level -- if the current climbs too high, it burns up the wire. Destroying the fuse opens the circuit before the excess current can damage the building wiring. The problem with fuses is they only work once. Every time you blow a fuse, you have to replace it with a new one. A circuit breaker does the same thing as a fuse -- it opens a circuit as soon as current climbs to unsafe levels -- but you can use it over and over again. The basic circuit breaker consists of a simple switch, connected to either a bimetallic strip or an electromagnet. The diagram below shows a typical electromagnet design. The hot wire in the circuit connects to the two ends of the switch. When the switch is flipped to the on position, electricity can flow from the bottom terminal, through the electromagnet, up to the moving contact, across to the stationary contact and out to the upper terminal. The electricity magnetizes the electromagnet (See How Electromagnets Work to find out why). Increasing current boosts the electromagnet's magnetic force, and decreasing current lowers the magnetism. When the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage. The entire linkage shifts, tilting the moving contact away from the stationary contact to break the circuit. The electricity shuts off. Click on the circuit breaker to release the switch.A bimetallic strip design works on the same principle, except that instead of energizing an electromagnet, the high current bends a thin strip to move the linkage. Some circuit breakers use an explosive charge to throw the switch. When current rises above a certain level, it ignites explosive material, which drives a piston to open the switch.
Transformers require a changing current to create the changing electromagnetic field that makes them work the way they do. In DC circuits, there is no change, so there is no w…ay for the transformer to create the field and transfer the energy.
A parallel circuit has more than one resistor (anything that uses electricity to do work) and gets its name from having multiple (parallel) paths to move along . Charges… can move through any of several paths. If one of the items in the circuit is broken then no charge will move through that path, but other paths will continue to have charges flow through them. Parallel circuits are found in most household electrical wiring. This is done so that lights don't stop working just because you turned your TV off.
Good question! I am a science freak. a tank circuit is basically a circuit of a capacitor and a inductor. A capacitor stores voltage, usually from a battery An inductor is a… coil of wires. Whenever a voltage (think of electricity)run across the inductor (think of it as running through it), it creates a magnetic field. basically the capacitor is filled up usually with a battery, and then it comes out the other end of the capacitor through the wire to the inductor which makes a magnetic field and the vice versa. They just keep exchanging.
A Thyristor is a Silicon Controlled Rectifier (SCR) which is functionally similar to a transistor. When voltage is applied to the gate, the SCR turns on (forward voltage onl…y) and conducts. If it is a DC circuit, the SCR will not turn off until the supply voltage is turned off; making the SCR almost useless as a DC switch. The SCR is useful in AC applications, allowing the engineer to effectively treat the SCR as a solid state switch. The SCR (thyristor) COULD be treated as a fuse though, if too much current is pushed through the thyristor/SCR it would blow out, preventing an over-current condition in the rest of the circuit.
i dont know, i want to know aswell. eeek. The RCB/RCD is placed between a 3-wire supply and its load, for example between a wall-socket and a kettle. The supply must be one wi…th a live, a neutral and an earth. In normal operation equal and opposite currents flow in the live and neutral wires, with no current in the earth wire. But under fault conditions there could be unbalanced currents in the live and neutral, with the balance flowing in the earth wire. That indicates danger and the device detects it and turns the power off. Most RCDs operate with a fault current of 10-30 milliamps, that is 0.01 to 0.03 amps.
You will need a battery, a wire, and a current for it to flow in to.
As the breaker is tripped, a magnetic coil is beneath it and as the movable contact falls into the coil the arc is elongated in a spiral caused by the magnetic coil until the …SF6 quenches the arc.
Answer A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction…, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
There is a temperature sensor in the motor. When it gets hot enough it completes a circuit and causes a relay to close and turns the fan on. There is power to the fan all the …time, the sensor and relay supply the ground for the fan Engine cools down, the sensor opens and shuts the fan off.
An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move.
A switch is used to connect or disconnect a load from a source of voltage. If you take the input and connect directly to the output the result is that the connected device is …always on.
