Basic Circuit Concepts

This set of MCQs helps students to learn about basic circuit concepts, describing about a circuit which is an unbroken loop of conductive material that allows charge carriers to flow through continuously without beginning or end. If a circuit is “broken,” that means its conductive elements no longer form a complete path, and continuous charge flow cannot occur in it.
