Question

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 15 k resistor is 5.0 W, what is the maximum allowable potential difference across the terminals of the resistor? B)A 9.0 k resistor is to be connected across a 120-V potential difference. What power rating is required? C)A 100.0 and a 150.0 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 resistor under these conditions? E)What is the rate of heat generated in a 150.0 resistor under these conditions?

Explanation / Answer

p=V^2/R V=sqrt(PV)=273.86v
