What else can I help you with?
What type of device is used to increase or decrease the voltage of an electric current-?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
Is an ammeter a device specially designed to measure current?
An ammeter is a measuring instrument used to measure the electric current in a circuit.
True or false A device that is used to open the circuit when the current flow is to great is a disconnect switch?
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.
Transistor is a linear or non linear circuit element?
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.
Where circuit breaker are used?
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.
What device used to open a circuit if too much current flows through it?
A circuit breaker is a device used to open a circuit if too much current flows through it.

Can a varistor be used as a circuit protection device?
No, a circuit protection device must open the circuit on a fault current or overload.
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.

What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
The device used to deenergize circuits automatically when a very small ground fault current flows is the?
A ground fault circuit interrupter is the device used to de-energize the circuit.
Can a voltmeter increase voltage?
No, a voltmeter measures voltage in a circuit but cannot increase it. It is a passive device that is simply used to read the voltage at a specific point in the circuit.
What is the name of a device that can be used to control the amount of current?
A resister limits the amount of current passing through a circuit.
