Most batteries have a voltage of 12V. Here is how many amp hours battery you need to power a 100W device for 8 hours: Ah = 800W / 12V = 66.67 Ah This means you will need a battery with at least 66.67 amp-hours (Ah). Here is the step-by-step procedure
Note that if you add the voltage drops across the two resistors, you get 9 volts, which is the total voltage supplied by the battery. That isn''t a coincidence; the battery is supplying voltage to the two resistors in the circuit, and the supply voltage is divided between the resistors proportionally, according to the values of the resistors.
The Energy of Batteries Measuring and Influencing Factors
E = V * C where E is the energy in watt-hours, V is the voltage in volts, and C is the capacity in ampere-hours (Ah). For example, a 12-volt battery with a capacity of 100 Ah has an energy of: E = 12 V * 100 Ah = 1200 Wh or 1.2 kWh This means that the battery can ...
