Two filament lamps, one rated 40W,220V and the other rated 100W,220V, are connected in series across a 220V mains supply.
(i) Calculate the resistance of each lamp at its rated operating condition.
(ii) When connected in series, determine the current flowing through the circuit.
(iii) For the series connection, calculate the power dissipated in each lamp.
(iv) Which lamp will glow brighter in the series arrangement? Justify your answer quantitatively.
