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

question 28

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 10-ohm resistor carrying a current of 1 ampere dissipates 10 watts.
How much power is dissipated in a 50-ohm resistor carrying a current of 9 amperes?

• A) \(P = 50\) Watts
• B) \(P = 45 \mathrm { Watts }\)
• C) \(P = 9 \mathrm { Watts }\)
• D) \(P = 4,050 \mathrm { Watts }\)
• E) \(P = 5\) Watts
