Question

Two points P and Q have electric potential of (-20) volt and (-30) volt respectively. These two points are connected by a metallic wire. Find the direction of flow of electrons and the direction of electric current through the wire. Justify your answer. pls tell the right answer i will mark brainliest for sure.

Answer 1

Given that,

The electric potential of P is (-20 V) and that of Q is (-30 V).

To find,

The direction of the flow of electrons and the direction of electric current through the wire.

Solution,

From the given data, it is clear that the potential of P is more than that of Q. We know that the electric current flows from higher to lower potential. The direction of the electric current is opposite to the direction of the flow of electrons.

So, electrons flow from (-30 V) to (-20 V) and the current will flow from (-20 V) to (-30 V).
