How a simple circuit works and what are the parts needed for it to work?

∙ 12y ago
The simplest circuit consists of a current source and a resistant element--for example, a battery and an LED bulb.
Circuits work by establishing a difference in charge across the terminals of the battery, which can be thought of as pulling or attracting electrons through the wires. The resistant element partially blocks the travel of the electrons, preventing the dangerous state of uncontrolled electron motion known as a short circuit.

Why does a circuit work?
It works with a connected wire and all the components inside a circuit.
How does an inclined plane reduce the forces needed to do work?
by increasing effort distance hence reducing the effort needed to work
Why do things stop working when you switch them off?
Electricity only works when it can flow all the way around a loop called a circuit. Turning off a switch breaks the circuit, stopping the flow and turning electrical things off. Turning a switch on joins the circuit and makes them work again.
How the magnetic piston works?
A magnetic piston works on the basic principals of magatism. The pistons are positions in a way that they meet their polar opposites and resist each other. This creates the motion needed to turn the pistons.
What law is used to find the polarity of a circuit?
It is possible that Kirchoff's law will answer this question. But why make it hard? It is customary to find the polarity of a circuit by simple inspection. Let's do a basic circuit and see how it works. Draw a square. Put a battery in the left side, and put the positive terminal down and the negative terminal up. Put a resistor in the right side. Two components - a simple series circuit. The battery will be "sending out" electrons from the negative terminal (the top one), and it will be "collecting them in" at the positive terminal (the bottom one). Put a "-" by the top of the battery to label that terminal. Now put a "+" by the bottom terminal. You've specified the polarities. Anyone looking at the circuit now can "find the polarity" of the circuit by inspection. Let's go one step farther. The electrons will be flowing out the top of the battery, and over and down through our resistor. Then they'll flow out the bottom of the resistor and across and into the bottom of the battery. Very simple, very easy. Now focus on this. The polarity of the voltage drop across the resistor is negative on the top and positive on the bottom. The end of the resistor into which current flows is said to be the negative end of the component, and the end out of which the electrons flow is said to be the positive end. Is this clear? Electrons flow out the negative terminal of a battery, and electrons flow into the negative end of our resistor. Be super clear about this. That's the way voltages are labeled in a circuit diagram. (The resistor "drops" voltage, while the battery represents a voltage "rise" in circuits.) For our circuit, the voltage drop across the resistor, which can be though of as the measure of voltage across the resistor, is negative on top and positive on the bottom. If you were going to measure the voltage drop across the resistor, the black meter lead would be on top of that resistor and the red lead would be on the bottom. If anyone encounters the circuit, the polarity will be obvious by inspection. We must be given a voltage somewhere, or we must be given a direction of current flow so we can make our inspection and determine polarity. If we were given nothing about our circuit except the direction of current flow, we'd know the rest by inspection. Take the simple circuit we made and take off all references to polarity. Now draw an arrow parallel to the top line of the circuit, and make it point to the right. If that arrow represents the direction of current flow, it would be telling us current was flowing clockwise around our square circuit. The polarities of all the other components (there are only two) would then be known. We would know by simply looking at the circuit what was happening, know by inspection. [This answer has a couple of simplifications, but not where it makes any difference. The answer was designed to supply fundamental knowledge or introductory information. It is unnecessary to say, for instance, that modern digital multimeters (DMMs) will measure voltage no matter what lead is placed where - the only difference being whether on not the "minus" sign appears on the DMM's display. Save that for later. We're keeping this simple.]
What components are needed to make an electric circuit works?
Globe Switch Wires(to connect) power Pack
How do you know when your circuit works?
You know your circuit works when it does what you designed it to do, and prefferably as little else as possible.
How is LED different from lamp?
similarity between lamp and LED- lamp in simple current is used to show that current is flowing and LED performs the same task but in electronic circuit .difference between lamp and LED-lamp in simple current is used to show that current is flowing and LED performs the same task more efficiently but in electronic circuit . so LED works more efficiently in electronic circuit than lamp which performs task in simple circuit.
What is schematic circuit?
a schematic circuit is a diagram that show you how a particular circuit works
Why does a circuit work?
It works with a connected wire and all the components inside a circuit.
Part of a circuit that does work?
Three basic parts of a circuit are: 1. Active components = source of energy 2. Transmission Lines = wiring and control devices 3. Passive components = load or user of energy
How does High and Low voltage cut out circuit works if voltage varies?
I assume you mean - 'Why does a circuit fail to work if the operating voltage is too high or too low?' A certain specific voltage is needed to overcome the natural resistance in circuit components. For instance in simple transistors, this is 0.7V to get the transistor to switch on and 1.4V is lost across the switched junction. This is why may circuits operate at above 3V. The rest of the circuit is designed to operate at the specified voltage and if you go too high, too much current will flow through the circuit and it will fail in the same way a fuse will blow if too much current is passed through it.
How a switch works when it is on and off?
The basic answer is that when it is off, the circuit is broken, when it is on, the circuit is complete. Example: _/_ is off ___ is on
