Amperage

the strength of an electric current measured in .
Abbreviation: amp.
Historical Examples

The amperage, on the other hand, is that of the six cells combined, or 150.
Motors James Slough Zerbe

Voltage, amperage, and watt or kilowatt are the terms in common use.
Foods and Household Management Helen Kinne

Then he defines the wave-form, voltage, and amperage entering the circuit and defines whatever is coming out.
With No Strings Attached Gordon Randall Garrett (AKA David Gordon)

The name plates on electric motors indicate the amperage at full load.
Electricity for the 4-H Scientist Eric B. Wilson

Then the voltage is lowered to a suitable rate, and the amperage raised in proportion, by special machinery, at the point of use.
Electricity for the farm Frederick Irving Anderson

That gun carried thousands of volts, with lots of amperage behind them, and if I had had a good hold on it I couldn’t have let go.
The Skylark of Space Edward Elmer Smith and Lee Hawkins Garby

It went out at a frequency of about 1,000 kilocycles, had an amperage of approximately zero, but a voltage of two billion.
