figure show 2 ways how 2 thin nichrome wires P and Q at fixed p.d. V are connected. Both P and Q are of the same length but the diameter of wire P is bigger than that of wire Q. When wire P and Q glow steadily in both circuit, which on of the following shows the comparison of brightness between wire P and Q in each connection? for series connection, i know that Q is brighter than P because p.d. across Q is greater ( resistance Q > resistance P ) for bout the parallel connection? i thought the brightness of P and Q should be same because p.d. across both P and Q are same but answer is P brighter than Q. any clue? and am i correct to compare brightness by comparing the p.d. ?
