Series Circuit Concepts

A series circuit is a circuit in which the components are connected in a single loop, with the current flowing through each component one after the other. The total resistance of a series circuit is the sum of the resistances of the individual components.

The relationship between voltage, current, and resistance in a series circuit is given by Ohm’s law: V = IR, where V is the voltage, I is the current, and R is the resistance.

Ohm’s Law and Series Circuits

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. In a series circuit, the voltage across each component is equal to the voltage across the entire circuit, and the current through each component is equal to the current through the entire circuit.

For example, if a series circuit has a voltage of 12 volts and a total resistance of 6 ohms, the current through the circuit will be 2 amps.

Kirchhoff’s Voltage Law

Kirchhoff’s voltage law states that the algebraic sum of the voltages around any closed loop in a circuit is zero.

In a series circuit, Kirchhoff’s voltage law can be used to calculate the voltage across each component in the circuit.

For example, if a series circuit has a voltage of 12 volts and three resistors with resistances of 2 ohms, 3 ohms, and 4 ohms, the voltage across the 2-ohm resistor will be 4 volts, the voltage across the 3-ohm resistor will be 6 volts, and the voltage across the 4-ohm resistor will be 8 volts.

Sample Problems and Solutions

Problem: A series circuit has a voltage of 12 volts and a total resistance of 6 ohms. What is the current through the circuit?

Solution: Using Ohm’s law, I = V/R, we can calculate the current as follows:

I = V/R
I = 12 volts / 6 ohms
I = 2 amps 

Therefore, the current through the circuit is 2 amps.
