Q2. What is the resistance of an automobile headlight through which 2.50 A flows when 12.0...
4. Power Consumption in Automotive Headlight Bulbs Suppose an automobile is designed with two headlights which each consume 100 W. The bulbs are powered by a 12 V electrical system. (a) Calculate the resistance of each bulb, assuming that the voltage across each bulb is 12 V and assuming that each bulb consumes 100 W. correct: (b) Suppose that the bulbs are connected incorrectly. that is, suppose they are connected in series rather than in parallel. 12 V P= 100...
An automobile battery has an emf of 12.6 V and an internal resistance of 0.0710 Ω. The headlights together have an equivalent resistance of 7.50 Ω (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.) 12.48 V (b) What is the potential difference across the headlight bulbs when the starter motor is operated, with 35.0 A of current in...
An automobile starter motor is connected to a 12.0 V battery. When the starter is activated it draws 150 A of current, and the batten, ' voltage drops to 7.0 V. What is the battery's internal resistance?
An automobile battery has an emf of 12.6 V and an internal resistance of 0.0840 Ω. The headlights together have an equivalent resistance of 7.90 Ω (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.) (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?...
