Power rating of a resistor. 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 [email protected] ω resistor is 5.0 w, what is the maximum allowable potential difference across the termi- nals of the resistor? (b) a [email protected]ω resistor is to be connected across a 120-v potential difference. what power rating is required? (c) a [email protected]ω and a [email protected]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, and what is the rate of heat generated in each resis- tor under these conditions?
