A car battery with a 12 V emf and an internal resistance of 0.097 Ω is being charged with a current of 47 A. What are (a) the potential difference across the terminals, (b) the rate Prof energy dissipation inside the battery and (c) the rate Pemf of energy conversion to chemical form? When the battery is used to supply 47 A to the starter motor, what are (d) V and (e) Pr?
A car battery has an emf of 12.0 V and an internal resistance of 0.20 Ω. While the car is running, the resistance of the rest of the car (the “load” resistance) is 1.00 Ω. What is the current through the battery? What is the terminal voltage of the battery? What is the power delivered to the rest of the car? What is the power dissipated as heat by the internal resistance of the battery?
