*"Amps.
By Multiplication:*"

From:Anonymous

Dividing shortcut, Hey if your like me, when you’re trying to figure out how many

amps. a piece of Equipment draws, long division is a hassle and I usually get it wrong, but multiplying is a lot easier.

Well with this shortcut you can use multiplication instead of division to divide watts by volts.

Example: usual way to figure how many amps. in 5000 watts with a voltage of 120 volts is to divide 5000/120=41.66 amps.

Shortcut : You multiply the watts 5000 by the reciprocal of 120 which will give you the same answer as dividing.

The reciprocals for these voltages are 120=.008333

208=.004807

230=.004347

277=.003610

480=.002083

Shortcut Example:

watts x reciprocal=amps

5000 x .008333=41.66

5000 x .004807=24.03

5000 x .004347=21.73

5000 x .003610=18.05

5000 x .002083=10.41

By the way to get the reciprocal of a number divide “1” by the number you want the

reciprocal of the result is the reciprocal.
