Laptop batteries are rated in W⋅h, the product of the power (in W) that the battery can provide and the time (in h) that it can provide this power. For instance, a 50 W⋅h battery can provide 50 W for 1.0 h, 25 W for 2.0 h, and so on. A 10.8 V laptop battery is rated at 76 W⋅h. What is the total charge the battery can provide to the laptop before the battery is depleted?

    Car batteries are often rated in amp-hours. This rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. The amp-hour unit is convenient for simple calculations. For example, a 60-amp-hour battery can supply a current of 1.0 A for 60 h (or 60 A for 1.0 h) before going dead. Find the energy stored in the following. (a) a 54 A-h, 14...

    The rechargeable batteries for a laptop computer need a much smaller voltage than what a wall socket provides. Therefore, a transformer is plugged into the wall socket and produces the necessary voltage for charging the batteries. The batteries are rated at 9.0 V, and a current of 194 mA is used to charge them. The wall socket provides a voltage of 120 V. (a) Determine the turns ratio of the transformer. Ns /Np (b) What is the current coming from...
