Question

why current is scalar quantity​

Answer 1

Answer:

To be precise, current is not a vector quantity. Although current has a specific direction and magnitude, it does not obey the law of vector addition. ... So, a current of 10 A leaves the junction

Explanation:

Answer 2

Answer:

Doesn't obey triangle law of vector addition.

Explanation:

According to the given question,

We are asked to find why current is scalar quantity.

To solve this question we have to know about scalar quantity and vector quantity.

• Scalar quantity-- It's the physical quantity which has magnitude but not direction.

• Example-- Mass, Current etc.

• Vector quantity-- It's the physical quantity which has magnitude and direction. And it obeys triangle law of vector addition.

• Example-- velocity, acceleration etc.

Thus, As the current doesn't obey the triangle law of vector addition. Hence it's not vector. Therefore, it's scalar quantity.
