What Is Surge Current?

- Jul 17, 2018-

Surge current: A piece of audio equipment consists of components such as resistors, capacitors, inductors, and transformers. They are all cold before starting up. When the power is turned on, its resistance is small, so the instantaneous current is very large, which is 2.5-3.5 times of the normal working current. This current is called a surge current, which can cause damage to the circuit.
