How much current flows through each of the three resistors connected in series if the total current is 3 amps?

• A. 3 Amps
• B. 1 Amp
• C. 2 Amps
• D. 0 Amps

Answer: (A)

In a series circuit there is only one path for the current, so the same current flows through every component. If the total current in the loop is 3 amps, that 3 amps must pass through each resistor in turn. The voltages across the resistors can differ (V = IR), but the current is the same through all of them. Values like 1 amp, 2 amps, or 0 amps would require the current to be different in different parts or no current at all, which isn’t the case here. Therefore, the current through each resistor is 3 amps.
