Two cylindrical resistors are made of copper (p=1.72x10^-8 ohm m). R1 has radius 2.00mm and length 1.00m. R2 has twice the radius of R1.
(a) Resistance of R1?
(b) length of R2 if it has the same resistance
(c) find how much current flow if either resistor were connected to 15V battery.
(d) what is the current density through each resistor?
(e) what is the current out of the battery if the resistors are connected in series?
