## What is not a vector of quantity?

Speed is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity. Answer: It has only magnitude and no direction, hence it is a scalar quantity.

Why electric current is not a vector through it has direction?

Explanation: In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the algebric sum and not vector sum (i.e it does not follow the parallelogram of vector addition). Hence it is a scalar quantity and is not a vector even though it has direction.

Is current velocity a vector quantity?

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

### Which type of quantity the current is?

scalar quantity
Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction.

What is not a scalar quantity?

The one which is not a scaler quantity is “Momentum”.

Which of the following quantities is not a vector?

In option (D) we have velocity which is also a vector quantity since it is having both magnitude and the direction. So, in the given options we see that only distance is the quantity which is not a vector quantity among all the four given quantities. So, the correct answer is “Option A”.

#### Is current a vector quantity or scalar quantity?

Complete answer: 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 .

Why current is a scalar quantity not vector?

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.

Is current scalar or vector quantity?

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 .

## Is current is a scalar quantity?

Is electric current a base quantity?

Electric current (I) was chosen by SI to be a base quantity – a fundamental physical quantity. A base quantity – though is not defined in terms of other quantities – can however be expressed in terms of other quantities.

Why is current not considered a vector quantity?

Current has both magnitude and direction. As per the definition of vector defined in encyclopedia, current should be a vector quantity. But, we know that current is a scalar quantity. What is the reason behind it? To be precise, current is not a vector quantity.

### Why is current considered to be a scalar quantity?

Current has both magnitude and direction. As per the definition of vector defined in encyclopedia, current should be a vector quantity. But, we know that current is a scalar quantity.

Why is current density J not a vector?

Electric current i is a scalar amount. Current Density J is a vector . The current is written in the form of I = J . A where A is the area vector, Now the question is why the current is not vector. The vector is not only the direction to be, it has some properties, which are not present in current .

Is the unit of current density a scalar or vector?

The unit of current density is the ampère per square meter, which has no special name. Despite being the ratio of two scalar quantities, current density is a vector. And the reason is, because it is.
