Detailed explanation-1: -A ‘switch’ is an electric device that is used to make or break a circuit. When the switch is in ‘OFF’ position, then the circuit is not complete.
Detailed explanation-2: -When the switch is off, the circuit is incomplete and hence, current will not flow in the circuit. Q. If an electric switch is open then no current flows through the circuit.
Detailed explanation-3: -When the circuit switch is off, no electricity will flow and then the circuit is called an open circuit.
Detailed explanation-4: -A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch. The terms “open” and “closed” refer to switches as well as entire circuits.
Detailed explanation-5: -Bipolar Transistors. The working of a transistor is similar to that of a normal switch. Power Diode. Silicon is used for the construction of the power diode. MOSFET.
