Q) How much power is being used in a circuit when the applied voltage is 13.8 volts DC and the current is 10 amperes?
A) 138 watts
NJ2X Notes:
It is useful to memorize the PIE triangle. By covering up one variable you get the equation. So in this example:
P = I * E
P = 10 Amps * 13.8 volts = 138 Watts
Easy as PIE!
