The power rating of a resistor is the maximum power the resistor can safely dissipate without too great a rise in temperature and hence damage to the resistor.
A. If the power rating of a 15kΩ resistor is 5.0 W, what is the maximum allowable potential difference across the terminals of the resistor?
B. A 9.0kΩ resistor is to be connected across a 120-V potential difference. What power rating is required?
C. A 100.0 Ω and a 150.0 Ω resistor, both rated at 2.00 W, are connected in series across a variable potential difference. What is the greatest this potential difference can be without overheating either resistor?
D. What is the rate of heat generated in a 100.0 Ω resistor under these conditions?
E. What is the rate of heat generated in a 150.0 Ω resistor under these conditions?
