Is electric current a scalar or vector?

Electric current is a scalar quantity, even though it has direction, because it does not follow the vector law of addition — currents add algebraically at a junction.

Is temperature a scalar or vector?

Temperature is a scalar quantity; it has magnitude only and no associated direction.

Difference Between Scalar and Vector

Physical quantities are classified as scalars or vectors depending on whether direction matters.

In short

A scalar has only magnitude (e.g. mass, speed, temperature); a vector has both magnitude and direction (e.g. velocity, force, displacement).

Scalar vs Vector — Comparison Table

Basis	Scalar	Vector
Magnitude	Yes	Yes
Direction	No	Yes
Addition	Ordinary algebra	Vector (triangle/parallelogram) law
Examples	Mass, speed, time, energy	Velocity, force, displacement, acceleration
