A light bulb used in a slide projector draws a current of 6 amperes when operating on 120 volts.
If two slide projectors are connected in series across the same 120-volt source, the current drawn from the source remains at 6 amperes.

Quizplus · Accepted Answer

When two slide projectors are connected in series, the total voltage across them is 240 volts (120 volts for each projector). The current drawn from the source would decrease as the total resistance of the circuit increases due to the addition of the second projector in series. Therefore, the current drawn would be less than 6 amperes.
