1. What is the smallest value of resistance that can be used across a 100 Vdc source if the
power dissipated is not to exceed 50 W?
2. If the voltage across a resistance is doubled, what will happen to the power absorbed by
the resistor?
3. A resistor of 100 Q has a charge flowing through it at the rate of 300 coulombs per
minute. How much power is dissipated?
4. A 10-kQ resistor has a rating of 100 W. What are the maximum current and the
maximum voltage that can be applied to the resistor?
5. A dc motor draws a current of 40A at 220V. If 800 W is dissipated in the form of heat in
the motor, how much power is available for mechanical work?
