Been doing a lil practical on capacitors. Tricky enough when the thing became clear. We used a joule meter so measuring energy rather than charge... So I've figured out how that works and the difference in energy and charge. I had to plot volts^2 / energy. Now we used a 25v/2200 uF capacitor. Charged it with 1 volt recoded the work done as it discharged. 1- 15 volts. First question - is the gradient on my graph just another way of saying capacitance? Secondly is there any way to relate this to the farad value shown on the capacitor we used?
