Series Circuit Analysis: Understanding Current Flow

What is the current through the motor in a series circuit with a motor, lamp, and battery?

The resistance of the motor is 10 Ω, the resistance of the lamp is 20 Ω, and the current through the lamp is 0.4 A.

Current through the motor:

The current through the motor in a series circuit is also 0.4 A.

When components are connected in series in an electrical circuit, the current flowing through each component is the same. This means that the current flowing through the lamp, which is 0.4 A in this scenario, would also be the current flowing through the motor. In this case, the current through the motor is also 0.4 A.

This principle of current being constant in a series circuit is a fundamental concept in electricity. It allows us to analyze and predict the behavior of circuits, ensuring that the components receive the necessary current to function properly.

Understanding how current flows in a series circuit is essential in troubleshooting and designing electrical systems. By grasping this concept, you can effectively diagnose issues and optimize the performance of your circuits.
