An automobile battery has an emf of 12.6 V and an internal resistance of 0.0700 . The headlights together have an equivalent resistance of 6.70 (assumed constant). (a) What is the potential difference across the headlight bulbs when they are the only load on the battery? (Enter your answer to at least two decimal places.) V (b) What is the potential difference across the headlight bulbs when the starter motor is operated, with 35.0 A of current in the motor? (Enter your answer to at least two decimal places.) V
