I need to be able to charge the 10F capacitor with a 3V solar panel, disconnect the solar panel, turn a switch and run the motor. I''ve tried to make a circuit on copper strip board but without success. I''d be extreamely gratefull on any assistance in charging and discharging capacitors. A circuit diagram would be perfect. Many Thanks.

At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge decreases is proportional to the amount of current, p.d or charge it has left

If you charge about 5 times the ''time constant,'' about 99.33% will be charged. The larger the resistance, the weaker the current flows. So it takes longer to charge. The larger the capacitance, the greater the need to charge it. So It takes a long time. Discharging the capacitor. Discharge of the capacitor also takes time.

Since charge builds up on a capacitor rather than flowing through it, charge can build up until the point that the potential difference ΔV=Q / C balances out the external voltage (electromotive force of the source) pushing charge onto the capacitor. The discharge of a capacitor in a RC circuit is the inverse process of capacitor charging ...
When a capacitor is charging, the way the charge Q and potential difference V increases stills shows exponential decay. Over time, they continue to increase but at a slower rate; This means the equation for Q for a charging capacitor is:; Where: Q = charge on the capacitor plates (C); Q 0 = maximum charge stored on capacitor when fully charged (C); e = the exponential function
