You have two light bulbs that you will connect to a 120-volt outlet (you can treat that as a 120-volt battery) - the bulbs can be placed in series with one another or in parallel with one another. The first thing you should do is to figure out the resistance of each bulb. We will assume the resistance of each bulb stays the same whether they are in series or parallel. Part (a) One of the light bulbs is labelled "120 V, 40 W" and the other is labelled "120 V, 90 W." If the bulbs are placed in series with one another, determine the equivalent resistance of the circuit. Part (b) == Homework Unanswered Due Feb 13th, 12:15 PM Continuing from part (b), calculate the current in the series circuit.
