WebIf you have a dc voltage of x volts, this is the maximum voltage you can get from it. If you have an ac voltage of x volts, the maximum voltage is more than x (I forgot how to calculate it, maybe it x 2, someone correct me if I'm wrong). This is because the voltage rating is the average of the oscillating voltage (after taking all positive). Web3 de mar. de 2024 · “High voltage” is a relatively arbitrary term, used to refer to electrical energy large enough to cause damage to humans.
