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 14.0 resistor is 4.6, 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 8.00 resistor is to be connected across a120potential difference, what power rating is required for that resistor?
