The Power, in Watts, Dissipated as Heat in a Resistor $\quad P = 50$

question 54

Multiple Choice

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 30-ohm resistor carrying a current of 1 ampere dissipates 30 watts.

• A) \(\quad P = 50\) Watts
• B) \(\quad P = 8\) Watts
• C) \(\quad P = 3,200\) Watts
• D) \(\quad P = 5\) Watts
• E) \(\quad P = 40\) Watts
