Question

Current is a vector physical quantity

• A. True
• B. False

Answer 1

The correct option is B False

1. When a physical quantity has both magnitude and direction, it is called a vector quantity. However, there are other elements that influence whether a quantity is a vector or scalar.
2. The physical quantity is considered to be a vector quantity, if it obeys the laws of vector addition, such as the triangle law of vector addition and the parallelogram law of vector addition.
3. When two currents meet at a junction in the case of electric current, the resultant current is an algebraic sum, not a vector sum.
4. Current reflects the flow of positive charge in one direction, but it is considered as a scalar quantity since it obeys scalar addition rules rather than vector addition laws, and the angle between the wires carrying current has no effect on the overall current in the circuit.

As a result given statement is false, despite having magnitude and direction, an electric current is a scalar quantity.
