If the current through the circuit is 2 a how many light


Several light bulbs, each of resistance 1.5 Ω, are connected in a series across a 120 V source of emf. If the current through the circuit is 2 A, how many light bulbs are there in the circuit?

Let n represent the number of similar resistors in a circuit. Each resistor has a resistance of r. When the resistors are connected in parallel the circuit has a total resistance of R. What would the total resistance of the circuit be if the resistors were instead connected in series?
