WebOct 26, 2016 · You can calculate the average by adding them all up and dividing by the number of readings assuming the interval between the readings or you can work out the charge by multiplying each reading by the time between it and the next one and adding all these up. You can then express this in ampere-hours or coulombs. Web5. You can derive it from the charge equation for a capacitor: Q=C*V. Rearranging it you have. V=Q/C. Since some of the values will be changing over time we have to express this equation in terms of time: V (t) = Q (t) / C (t) C (t) is a constant - capacitance never changes, so the equation can be simplified: V (t) = Q (t) / C.
