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.

# Which unit of electricity does the work in a 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.

# What is an electrical circuit and how does it work?

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

# How the circuit work?

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

# How air circuit breaker works?

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

# Why do transformers not work in DC circuits?

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

# How does a parallel circuit work?

  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

# How does a tank circuit circuit work?

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

# What does a thyristor works as a circuit breaker?

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

# How does a rcb circuit breaker work?

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

# What are the components needed for a circuit to work?

You will need a battery, a wire, and a current for it to flow in to.

# How sf6 circuit breaker work?

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

# How does clipping circuits work in lab?

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

# How does the cooling fan circuit work?

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

# What makes circuits work?

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.

# Will a circuit work with the switch and will it work if you take the switch out of the circuit?

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

# Why would a circuit not work?

A circuit works based on a closed circuit(a complete circuit)and electricity supply.If without anyone of them,a circuit is not able to work.
