# Question

A cylindrical resistor is made of carbon and is 10.0 cm long with a diameter of 1.00 cm. Assuming the resistor is kept at room temperature,

(a) What is its resistance?

(b) If it is then connected to a 12.0-V battery, how many electrons pass through one end of The resistor in 1 min?

(c) In that 1 min, how much stored energy did the battery lose?

(d) Repeat these calculations for the resistor if it is sliced in half lengthwise.
