How does a capacitor reduce voltage drop in a DC motor start?
I know that a capacitor stores charge:
C=Q/V
but what i don't understand is how this would reduce the voltage drop caused by high current draw. … and if it this isn't true how is capacitor supposed to be set up then? what would happen if the capacitor is in series? …

What is the formula for charging a capacitor with constant current?
I read that the formula for calculating the time for a capacitor to charge with constant voltage is 5·τ = 5·(R·C) which is derived from the natural logarithm. … In another book I read that if you charged a capacitor with a constant current, the voltage would increase linear with time. Is this true, and if it is, what is the formula used for calculating this? …
