Question

There is a circuit of 2 lamps in a series. If a voltage of 6 volts is impressed across the circuit and the voltage across the 1st lamp is 2 volts, what is the voltage across the second lamp? Defend your answer

I want to say that the second lamp has a voltage of 4 volts as well because the amount of energy supplied to the total current is equal to the sum of energies supplied to each device.

Is this right?

Answer 1

The sum of the voltage drops has to equal the source voltage. Correct.
