The pull-up resistor is a commonly used component in electronic circuits,
The selection of pull-up resistors is crucial,
The functions of pull-up resistors and pull-down resistors are exactly opposite.
Varistors are semiconductor electronic components whose resistance values vary with the voltage applied to them
Power Stability: The use of varistors in transformers and power equipment can smooth out peak voltages in the power supply and provide more stable power output.
The varistor quickly transitions to a low resistance state,
