The power rating of a resistor is the maximum power it can safely dissipate without being damaged by overheating.

A) If the power rating of a certain 17k? resistor is 4.0W , what is the maximum current it can carry without damage?

B)What is the greatest allowable potential difference across the terminals of the resistor in part A?

C)If a 8.2k? resistor is to be connected across a 120V potential difference, what power rating is required for that resistor?
