Amperage and Voltage

.
The strength, or amperage, of an alternating current varies continuously between zero and a maximum. Since it is inconvenient to take into account a whole range of amperage values, scientists simply deal with the effective amperage. Like a direct current, an alternating current produces heat as it passes through a conductor. The effective amperage of an alternating current is equal to the amperage of a direct current that produces heat at the same rate. In other words, 1 effective amp of alternating current through a conductor produces heat at the same rate as 1 amp of direct current flowing through the same conductor. Similarly, the voltage of an alternating current is considered in terms of the effective voltage.
