Series Circuit

Series Circuit A series circuit has only one path for the current so the current is the same at any point in the circuit.

A series circuit contains a 12-V battery and three bulbs with resistances of 1Ω, 2 Ω, and 3 Ω. What is the current in the circuit?

The circuit shown at right contains a 9-volt battery, 1-ohm bulb, and a 2-ohm bulb. Calculate the circuit’s total resistance and current. Then find each bulb’s voltage drop.

What is the equivalent resistance of the following circuit? What is the current in this circuit? 9 V
