Compute all parts of given problem:
Problem: A potential difference of 0.90 V will be applied to a 29.0 m length of 18-gauge copper wire (diameter = 0.0400 in.). Calculate the following values.
Part A: What is the current?
Part B: What is the rate at which the thermal energy will appear in the wire in W?
I need help to find the rate at which the thermal energy will appear in the wire.
