WebA relay switch circuit can be designed using NPN transistor. In case of NPN transistor as shown in fig when V1 is 0v or turn off then base current ( ib ) will not flow due to which transistor remain in cut-off region and hence ic will not flow and relay coil remain de-energized but when base current ( ib ) is provided sufficiently the maximum amount of … WebCircuit design BJT ON/OFF created by attiliorussostrada14VE7HL with Tinkercad
