Question
Which of the given physical quantities is/are not a vector?
- Electric force
- Electric field strength
- Electric charge
- Electric Force and Electric field strength
Hint:
The electric charge has only magnitude and no direction. Thus, it is a scalar quantity.
The correct answer is: Electric charge
Electric current is a scalar quantity. Any physical quantity is defined as a vector quantity when the quantity has both magnitude and direction but there are some other factors which show that electric current is a scalar quantity . When two currents meet at a point the resultant current will be an algebraic sum.
