Battery Capacity Calculator
Battery capacity calculator converts between amp-hours and watt-hours. As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I: P = V × I As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the …

4.11 DC Circuits Containing Resistors and Capacitors – Douglas …
Since the resistance and capacitance are given, it is straightforward to multiply them to give the time constant asked for in part (a). To find the time for the voltage to decline to 5.00 x 10 2 V, we repeatedly multiply the initial voltage by 0.368 until a voltage less than or equal to 5.00 x 10 2 V is obtained.
