Hi I am confused about an example in my textbook related to charge stored by a capacitor A 100 uF capacitor and a 700 uF capacitor are placed in series, along with a cell of 3V. Calculate the p.d. across the 100 uF capacitor. The book states the solution as follows: "Using the reciprocal...

All energy is conserved. So if I push on an object and it doesn't move, where does that energy go?

Gotcha :) Thanks very much all of you for quick and concise replies. Have a good day :D
