Two identical lamps, with resistance R = 2 Ω, are connected to a source with Ɛ = 8 V and negligible internal resistance. Calculate the current passing through each lamp, the potential difference through each lamp and the power supplied to each lamp and the entire circuit, assuming that the lamps are connected (a) in series and (b) in parallel. (c) Suppose that one of the lamps burns out. What happens to the other lamp in the case of a series connection? And in the case of parallel connection?
