A car battery does 360 J of work on the charge passing through it as it starts an engine. (a) If the emf of the battery is 12 V, how much charge passes through the battery during the start? (b) If the emf is doubled to 24 V while the work remains the same, does the amount of charge passing through the battery increase or decrease? By what factor?
