Question

Is electric current a scalar quantity ??


No spam plzzz..... and I m giving 100 .... I want the answer with explaination ...

Answer 1

When it comes to this question, the common answer is → Although the current has a magnitude and direction, but because it does not conform to the vector algorithm, the current is a scalar, not a vector. Such an answer is a bit far-fetched.

The problem is actually very simple ! There was a mistake of stealing the concept here ! We confuse the two things current and current intensity.

• Electric current is a physical concept. It refers to the directional movement of electric charge. It is a physical phenomenon. It is not a physical quantity at all ! Therefore, although it has size and direction, it cannot be said that it is a vector or a scalar. The size of the current is called the current intensity (we often refer to it as current, but this current is not the other current), it is a physical quantity, but it has only the size and no direction, so the current intensity (current) is a scalar quantity.

Answer 2

Yes

Electric current is often termed as scalar quantity

Because it doesn’t follow the parallelogram law of vector addition ......

But it has DIRECTION

In physics any quantity having direction ...... which doesn’t follow the vector law or parallelogram law of addition is termed as TENSOR quantity .....
