Series Circuit Voltage Property (Lesson 4d)

In any Series Ciurcuit, the total voltage of the circuit (Vt) is the sum of the inmdividual voltages across each component.

This property of Series Circuits is the basis for the Voltage Divider Rule. By this property, the total voltage (Vt) can be found by adding the individual voltage across each component of the circuit.

Expressed in Algebraic Form: Vt = V1 + V2 + V3 .....+ Vn
where n is the last component of the circuit.

As you can see from Diagram above, the total voltage (Vt) of the Circuit is the sum of the voltages across each component. Vt = 2 V + 4 V + 6 V or 12 V.

Ohm's law can be applied to find the current through any Resistor. By the Current Property of Series Circuit, the current through one Resistor is the same through any other Resistor.
Current through Resistor a = 2 V/1 ohm = 2 Amp.
Current through Resistor b = 4 V/2 ohms = 2 Amp.
Current through Resistor c = 6 V/3 ohms = 2 Amp.
