Question

11. if a motor requirs 750watts and the input current amps is 12 amps what resistance is needed [​

Answer 1

Power=current^2*Resistance
So, Resistance=power/Current^2
Therefore: Resistance=750/(12*12)
Which equals resistance=5.20 ohm

Answer 2

Answer: 5.20833333 ohms (R)

Step-by-step explanation:

Resistance is that equal to power (watts) divided by the squared current of amps. R = P/A^2
