Question: How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms? 

How?: 

Equation: P = I^2 R          

Meanings:
P = Power in Watts
I = Current in Ampere
R = Resistance in ohms.

Plugged in: P = 36^2 x 3.9 = 5054.4
 
Answer: P= 5100 watts.

HOPE THIS HELPS! ^_^
