A wire of length 0.05 m, radius of 0.002 m has a current running through it at a constant rate. a) What is the current if 2 C of charge pass through it every 4 seconds? b) What is the resistance of the wire if p = 1.7 x 10^-80m? c) What is the potential difference across the wire? d) How much power is lost as the current passes through the wire?
