Ac current formulas are:
Ohm's law for reactive circuits:
Ohm's law for circuits containing resistance and reactance:
Current across the primary (Ip) of a transformer:
Current across the secondary (Is):
Human reaction to electrical shock is determined by the amount of current
flowing through the body. A 100-milliampere shock for 1 second is usually fatal!
