Question

What is the power dissipated by a 50.0 ohm resistor?

a. 0.743 w
b. 1.49 w
c. 2.08 w
d. 12.5w
e. none of these​

Answer 1

The power, in watts, dissipated as heat in a resistor varies jointly with the resistance, in ohms, and the square of the current, in amperes. A 15-ohm resistor carrying a current of 1 ampere dissipates 15 watts. How much power is dissipated in a 5-ohm resistor carrying a current of 3 amperes?
