Question

Is current is a vector quantity or scalar quantity?

Answer 1

scaler

Answer 2

vector
i think this

Answer 3

no not a vactor

Answer 4

whay

Answer 5

vector has both magnitude and ntdirection......if u have a sq loop u say at edge curret has 2 drxns.....but thats absurd......

Answer 6

Correct, current is not a vector. In equations that require a vector (for example a force on a wire carrying current) the direction of the wire is used as the vector as "dl". The current only serves to scale the vector, hence it is a scalar.

Answer 7

current is not a vector quantity since it dosen't add like a vectro quantity.

Answer 8

Current is most definitely a scalar quantity. In electromagnetics, current is defined as the surface integral of the dot product of J and ds. Dot products always give a scalar quantity.\[I = \int\limits_{?}^{?}J*ds\]

Answer 9

Current I is a scalar. Current density J is a vector. It is much similar to speed and velocity or distance and displacement. Current is defined as the amount of charge that flows through a unit cross section in unit time. Direction does not matter here. only the flow of charge is taken into account. Hence current is a scalar quantity

Answer 10

current does not follow the law of vector addition.current is a scalar quantity

Answer 11

scalar quantity
