A car battery with a 12 V emf and an internal resistance of 0.040Ω is being charged with a current of 50 A. What are
a) the potential difference V across the terminals.
b) the rate Pr of energy dissipation inside the battery.
c) the rate Pemf of energy conversion to chemical form?
When the battery is used to supply 50 A to the starter motor, what are
d) V and
e)Pr?
