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?
