A voltage supply of 400 V is connected across capacitors of 3 μF and 6 μF. Calculate the energy stored in 3 μF. (Duplicate of Q76, but missing 'in series'? It says 'across capacitors of 3μF and 6μF' which could be series or parallel. Usually, if not specified, it might be series, as in previous. But let's assume series, as before.
