Why can birds perch on the bare wire of a 100,000-volt power line without being electrocuted?

A battery with negligible internal resistance is connected to a resistor. The power produced in the battery and the power

dissipated in the resistor are both P1.

Another resistor of the same kind is added, so the circuit consists of a battery and two resistors in series.

(a) In terms of P1, now how much power is dissipated in the first resistor?

(b) In terms of P1, now how much power is produced in the battery?

(c) The circuit is rearranged so that the two resistors are in parallel rather than in series. In terms of P1, now how much

power is produced in the battery?
