Question

A continuous and closed path of an electric current is called an

• A. electric charge
• B. electric conduction
• C. electric potential
• D. electric circuit

Hint:

Think of a water analogy: Electric current is like the flow of water, and an electric circuit is like a closed pipe system that allows the water to continuously flow.

Answer 1

The Correct Option is D

Step 1: Understand the definition of electric current.
Electric current is the flow of electric charge. For this flow to be sustained and useful, it needs a complete path. Step 2: Analyze the given options. \begin{enumerate} \item Electric charge: This is the fundamental property of matter that can be either positive or negative. It is what flows to constitute an electric current, but it is not the path itself. \item Electric conduction: This refers to the movement of electric charge through a material. It describes how current flows but not the closed path required for a continuous current. \item Electric potential: This is the electric potential energy per unit charge at a point in an electric field. It is a measure of the potential to cause current to flow but is not the path of the current. \item Electric circuit: This is a closed loop or network of electrical components through which electric current can flow. The continuity and closed nature of this path allow for a sustained flow of charge. \end{enumerate} Step 3: Identify the correct term for a continuous and closed path of electric current.
Based on the definitions, an electric circuit is the continuous and closed path required for an electric current to flow.
