That is what the Earth wire does. Normally it does not carry current but it has this important safety function.

What is a Darlington IC?

Darlington circuit is voltage follower circuit with high input impedance and low output impedance.Darlington IC must have this ciruit integrated on it..


But in DC ciruit there is no current when capacitor is connected?

This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.


Where does the energy come from to amplify the signal in a amplifier?

The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.


If there are 4 ammeters in a parallel ciruit and one reads 0.8 what do the rest read?

If there are 4 ammeters in a parallel ciruit and one reads 0.8, the readings of the rest are indeterminate, because it depends on the individual branch resistance. !st answer, again, but better worded . . . Assuming that the 4 ammeters are in parallel with each other, and otherwise in a series circuit, then they all read the same.


What is the total resistance in a parrellel ciruit?

The rule for finding total resistance in a parallel circuit is that a parallel circuit has two or more paths for current to flow through. Another rule states that voltage is the same across each component of the parallel circuit. If one of the parallel paths is broken, current will still continue to flow in all the other paths.

In order to have current flow what must a circuit be?

the ciruit must be closed so it can move freely

When you add resistors that are in a series to a ciruit?

You raise the total resistance by that amount if added in series to a circuit. If you add them in parallel to a circuit then that total resistance will be less than the total of the added circuit.


But in DC ciruit there is no current when capacitor is connected?

This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.


Is a parallel circuit brighter than a series circuit?

Both are same. Only thing it depends upon the incoming voltage. In series ciruity if one bulb fails, the ciruit continuity breaks . In case of paraleel circuit even if one bulb fails the circuit continuity will not get affected


What is starter in tube light?

Starter is asmall device in a fluroscent tube light to start the ciruit. Once lit, starting circuit cuts off automatically


What is a electromechanically relay?

A relay is an electronic switching device that opens or closes a circuit. An electromechanical relay would be one that is opereated remotely using an electrical circuit that mechanically operated the relay, which in turn opens/closes the second ciruit.


How can a broken wire affect a series circuit differently than a parallel ciruit?

In a series circuit, a broken wire will interrupt the flow of current and cause all components to stop working. In a parallel circuit, if one wire is broken, the components in that branch will stop working, but components in other branches will continue to function.


Why is an energy source needed in order to have a working electric ciruit?

An energy source is needed to provide electrical energy to the circuit components such as resistors, capacitors, and bulbs. Without an energy source, there would be no electrical current flowing through the circuit, and no power for the devices to operate.

What is a complete electric ciruit?

A complete electric circuit is a closed loop through which an electric current can flow. It consists of a power source, such as a battery, wires to carry the current, and a load, such as a light bulb or motor, that operates using the current. If any part of the circuit is broken, the flow of electricity will stop.
