Why is it that Electricity is a scalar quantity but at the same time, electricity has both direction and magnitude?
I get that Triangular law of vector addition sh8t but still desperately in search of an answer.
Answers
Explanation:
You are right that current has a magnitude as well as direction, so it should be called as vector quantity. Let me take an example to show where does a current violate vector analysis.
check the attachment,
if you observe while applying KCL we are not considering the angles between the current but directly considering currents as Incoming and Outgoing. Hence, laws of vector addition are being violated so current cannot be referred to as Vector Quantity.
You can also think in this manner that current is nothing but the flow of electrons so at any node no matter the direction in which electrons arrive, the total number of electrons will be sum of electrons coming from every direction. Hence, current will also be sum of current coming into that node.
Answer:
Explanation:
Electricity is a scalar quantity because when electric currents meet at a junction,the resultant current will be an algebraic sum which means that
its magnitude won't be constant and not vector sum.So its a scalar sum
