Step 1

Given: R = 5.1 ohm

r = 0.69 ohm

emf = 4 V

t = 2.1 min = 2.1 × 60 = 126 seconds

Find: (a) The energy transferred from chemical to electrical form in the battery.

(b) The energy dissipated as thermal energy in the wire.

(c) The energy disspated as thermal energy in the battery.

Step 2

(a) Calculate the energy transferred from chemical to electrical form in the battery as:

Energy = power × time

Step 3

(b) Calculate the energy disspated as thermal energy in the wire:

...
