A Galvanometer can be used to detect the presence of current in a circuit.
An ammeter can be used to know the magnitude of the current flowing through the circuit.
The free electrons flowing in the circuit decrease.
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
Yes, electricity is wasted if a socket is switched on but not being used because the electricity is still flowing through the circuit even though no device is drawing power.
Electrical testers are used to determine if electricity is flowing through a circuit. An electrical tester such as a voltage meter can be used. To use the meter, insert the end of the tester into the socket or next to the electrical wire to be tested. If there is electricity flowing then the meter may beep or flash.
A resistor is a component that limits the flow of electric current in a circuit, while an insulator is a material that restricts the flow of electricity. Resistors are used to control the amount of current in a circuit, whereas insulators are used to prevent the flow of electricity altogether.
A switch is a device used to break a circuit. By opening the switch, the circuit is interrupted and electricity stops flowing. This allows for controlling the flow of electricity to different components in a circuit.
A multimeter set to measure current (in amperes) would be used to measure current flowing in a circuit. The multimeter needs to be connected in series with the circuit to accurately measure the current.

An insulator is used in a circuit to prevent electricity from flowing where it shouldn't, ensuring that current flows only through the intended path. Insulators are typically placed around conductive materials or components to maintain the desired circuit layout and prevent short-circuits or other electrical issues.
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
Yes, it is true.
Diodes perform a different function as switches. switches allow you to control wether or ot electricity is flowing. diodes only allow power to flow in one direction. A light emitting diode may be used as an indicator for wether or not power is flowing through a circuit.
