A watt (W) is the unit …
watt-hour = volts ∗ amps-hour. So, if we have a solar power system whose 12v battery has a capacity of 100Ah, its energy in watt-hours would be: 12 ∗ 100 = 1200Wh. Then, we can convert watt-hours back to battery capacity by dividing the value of watt-hour by battery voltage: 1200 12 = 100 Ah.
An air conditioner has a wattage rating of 1,000 watts and the time period it is used for is 4 hours in one day then the watt-hour is: Watt-hour (Wh) = watts x hours. = 1,000 x 4. = 4,000. Calculation: Appliance watts x hours used per day = daily watt hours consumption. To calculate watt-hours when joules are given, multiply the number of ...
