Voltage doesn't "pass through" anything. A voltage is a measure of the potential difference between two points. Maybe you're misunderstanding something.

We first have any awear ness approximately style of that merchandise that appx. What volume of electricity has been performed by skill of it and then additionally having awearness that wherein approx. voltage it rather is opereted then we will additionally end approximately its resistors, voltage,and contemporary of it.
