Transformer or instrument transformer. It can increase and decrease current output.
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
An ammeter is a measuring instrument used to measure the electric current in a circuit.
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
A circuit breaker is a device used to open a circuit if too much current flows through it.
No, a circuit protection device must open the circuit on a fault current or overload.
A switch is a device that stops and starts current flow in a circuit.
An ammeter is a measuring instrument used to measure the electric current in a circuit.
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
A ground fault circuit interrupter is the device used to de-energize the circuit.
A resister limits the amount of current passing through a circuit.
It depends on the amount of resistance, or load, the device is on the circuit. Do you have a particular device you're asking about?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
