Why electric current does not follow vector law of addition?

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 electric current is scalar or vector quantity?

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

Is electric charge scalar or vector?

Electric charge is a scalar quantity because charge never graduated into the level of vectors or tensors that need both magnitude and direction.

Is electric current a fundamental quantity?

The current can also be derived if we know the no of charges flowing in the conductor. Thus current is considered as the fundamental physical quantity and charge is a derived quantity.

Why electric current is opposite to electron flow?

Electrons being negatively charged flow from the negative terminal to the positive terminal of the voltage source. So, the actual direction of current should be from negative to positive terminal. So, the current flow is considered in the direction opposite to the direction of flow of electrons.

Is electric current a scalar or a vector quantity give reason?

Note: Current is a vector because it has a magnitude and a direction. But the thing is a vector always obeys the law of addition of vectors. Since current doesn’t obey it and it follows algebraic addition, currents are scalar.

Which of the following does electric current not follow?

Answer: (C) Solid sodium chloride is your answer.

Is electric current a vector?

Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. But there are other factors that determine the quantity as vector or scalar quantity.

Why electric current is scalar or vector?

Why electric current is a scalar quantity? In the case of electric current, when two currents meet at a junction, the resultant current of these will be an algebraic sum and not the vector sum. Therefore, an electric current is a scalar quantity although it possesses magnitude and direction.

Why is current not a vector quantity?

Because current is the charge passing through some surface in unit time (usually phrased as “charge passing a point in unit time” in circuits). That’s not a vector quantity – fundamentally, it’s just a count of electrons (or other charge carriers).

Is electric current a vector or scalar amount?

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 current in a thin wire a vector or scalar field?

The electric current is another vector field, but the current in a thin wire is approximately constant (but in the direction of the wire) over the cross section and along the length between connections, so is usually treated as a scalar (just like speed versus velocity).

Why is the electric field a vector field?

The electric field is a vector field, meaning that it assigns to every point in space a vector, which is the electrostatic force vector that a point charge of +1 coulomb would experience if it was placed at that point.
