In a DC, 12 volt circuit supplying a single lightbulb, voltage drop across the load is measured at fractionally under 12 volts. When a second identically rated bulb is wired in series with this circuit, approximately how much voltage should dropped across each bulb?
A) 24 volts
B) 12 volts
C) 6 volts
D) 4 volts

Question

Quizplus · Accepted Answer

When two identical bulbs are wired in series in a 12-volt circuit, the total voltage drop (12 volts) is divided equally between them, resulting in approximately 6 volts dropped across each bulb.
