If three voltage drops in a series circuit are 2V, 4V, and 3V, what is the total voltage drop?

9V

In a series circuit, the voltages across each component add up to the total supply voltage because the same current flows through every part. So the three drops of 2 V, 4 V, and 3 V must sum to the total: 2 + 4 + 3 = 9 V. The total voltage drop is 9 volts.

8V

7V

6V
