What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
A break in the wires of an electric current will the circuit and the current?
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
Impedience of electric circuit?
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
Impedance of electric circuit?
The impedance of electric circuit refers to the measure of the opposition that a circuit presents to a current when a voltage is applied.
What is an electric circuit with little or no resistance?
A: As current approaches infinity on a device it is known as a current source.
What is the Function of fuse in an electric circuit?
A fuse places a limit on the amount of current that can be drawn by an electric circuit by opening (blowing or melting) when the current exceeds a preset limit. This protects the circuit and the surroundings from fire or damage in the case of an overload or short circuit.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
What happens to an electric current when a circuit is closed?
If the circuit is closed the electric current will be closed as well.
A break in the wires of an electric current will the circuit and the current?
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
Why can't an electric current exist if the circuit is broken?
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
What is the name for the status of a circuit that has breaks which electric current that cant flow?
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.
A device that protects a circuit from current overload is called what?
Fuse, Circuit breaker
Is not essential to obtain electric current?
Electric circuit
An electric what is a pathway for electric current?
A closed circuit.
What a device that protects an electric circuit from too much current?
Circuit Breakers and Fuses limit the amount of current flowing through the circuit.
