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?

6) Car batteries supply a "nominal 12V voltage, but due to the internal resistance of the battery the actual voltage can be somewhat smaller. Consider this situation: Cars have an electric starter motor that draws 90A of current to turn over the engine pistons and start the car. While this 90A current is being drawn from the battery, the terminal voltage across the battery drops down to 11V. Use this information to find the internal resistance of the battery.

(a) A car battery with 12 V emf and internal resistance 0.05 is supplying a current of 50 A to the starter motor. Calculate the terminal voltage across its terminals of the motor? At what rate energy is dissipated in the battery? (3 marks) (b) Alisha is afraid of darkness and so sleeps with a 7.5W night light bulb on. She turns it on before getting in bed and tums it off 8 hours later. Determine the annual (365 days)...

1. A 12-V car battery has an internal resistance of 0.020 Ω. When the headlights and stereo are on, a current of 25.0 A is drawn from the battery. What is the value of the terminal voltage when this current is drawn from the battery? 12 V, 9.0 V, 12.5 V, or 11.5 V 2. A car battery seems to be malfunctioning (not providing the proper voltage and current to start your car). While the car is off and you...

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 battery has an emf of 12.0 V and an internal resistance of 0.050 0. Its terminals are connected to a load resistance of 3.00 V.
