We asked the students why the current is a scaler quantity?
98% of students answered that it is a scaler quantity because it doesn't follow the vector law of addition which is a wrong explanation.
Because current density is a vector quantity but it also doesn't follow the vector law of addition.
Many students came up with the assertion that current is a tensor quantity which is an obvious thing because every quantity is called a tensor and then we have different degrees of those tensors.
In this video, NMS sir came up with the correct explanation why current is a scaler quantity and why current density is a vector quantity.
Moreover he also discussed the real logic behind calling quantities as vectors or scalers.
Check out the complete video to unlearn some wrong concepts and learn a new fundamental concept about vector quantities.
