A car owner forgets to turn off the headlights of his car while it is parked in his garage. If the 12.0-V battery in his car is rated at 150.0 A ยท h and each headlight requires 41.4 W of power, how long will it take the battery to completely discharge?

  • Physics -

    Calculate the amperage of the lights:

    watts/volts= Amps.

    Then divide the battery's capacity by the answer.
