Isolation between power and control circuits is necessary to prevent high voltages or currents from affecting sensitive control components, ensuring safety and reliability of the control system. It also helps in preventing electromagnetic interference and noise from the power circuit, which could disrupt the control signals and lead to system malfunctions.

Is a switch needed to make a circuit work?

Yes, a switch is needed to control the flow of electricity in a circuit. It allows you to open or close the circuit, which determines whether the electrical current can flow through it or not. Without a switch, the circuit would be always on and the device connected to it would not be able to be turned off.

Why switch is always connected in the phase?

Switches are used to isolate the supply voltage from the connected load. This isolation is needed to be able to work on equipment in the de-energized state. Without the switch in the circuit this could not be accomplished.

What supplies energy to move elecricity through a circuit?

In a circuit, the energy needed to move electricity is provided by a power source such as a battery or a generator. This power source creates a voltage difference between the circuit's components, which pushes the electric charges to flow through the circuit.
