Physical Science: Series Circuit
posted by Britney on .
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?
The sum of the voltage drops has to equal the source voltage. Correct.
