Hey guys i dont really have a clue on how to attempt to answer this question:
Ex 3: A 50 F capacitor is charged from a 200 V supply and after being disconnected is immediately connected in parallel with a 30 F capacitor. The 30 F capacitor is initially uncharged. Calculate:
(a)the p.d. across the combination;
(b) the electrostatic energy stored before and after the capacitors are connected in parallel. Account for any difference in energy stored.
[125 V, 1 J, 0.625 J]
Could anyone help me? The answers to the above question are in the [ ]
Thanks, Greg
