A 24.0 V battery is attached across a length of gold wire with a radius of 0.600 mm.
(?????=2.35×108Ω?

ρgold=2.35×10−8Ωm)
(a) If you want the current to be 1.00 mA, how long does the wire have to be?
(b) What is the current density?
(c) How much energy would be delivered to the wire in 1 hour?(hint find power first)
