20.1 Current
Note that the direction of current flow in Figure 20.3 is from positive to negative. The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move.
How To Calculate Battery Amp Hours
In order to calculate the battery capacity in Ah, you will need to know the device''s power requirements in watts and the amount of time it will be used for. Once you have this information, you can use the following formula: Ah = (watt-hours / voltage) x discharge rate. Here, watt-hours is the amount of energy consumed by the device in one …
