Two resistors of 4Ω and 6Ω are connected (a) in series and (b) in parallel across a 220V supply.
(i) For each arrangement, calculate the current supplied by the source.
(ii) For each resistor in both arrangements, compute the power dissipated.
(iii) Compare the total power taken from the supply in the series arrangement with that in the parallel arrangement. Which connection draws more power and by what factor?
