Why should a circuit have low output impedance and high input impedance?

2019-06-17

You know, high input impedance actually means that the circuit absorbs less power from the power source (or the output of the previous circuit), which is allowing the power source or the previous stage to carry more loads. There is no doubt that it wou

What is the difference between a relay and a fuse and a circuit breaker?

2019-06-12

Relay: As the bimetal deformation reaches a certain distance, the control circuit will be disconnected so that the contactor is about to lose power and the main circuit is also disconnected, that is how a relay realizes overload protection to the motor.
