Question

Conventionally the direction of current is taken as
(a) the direction of flow to negative charge
(b) the direction of flow of atoms
(c) the direction of slow of molecules
(d) the direction of flow of positive charge

Answer 1

Hint: The direction of current can be seen in two different perspectives, one is by the direction of flow of positive charge, another one is considering the direction of flow of negative charge. Charge is taken into consideration because electric current itself means flow of charge. Use this concept to get the right answer.

Complete Step-by-Step solution:

Conventionally the direction of current is considered as direction of flow of positive charge from the positive terminal of source throughout the circuit and goes into the negative terminal of the source.
It is just a convention; it is not the absolute direction of current as the direction which is used to describe the direction of current in the electrical circuits.
So conventionally, the direction of the current is taken as the direction of the flow of positive charge as shown in the figure.

Hence option (D) is the correct answer.

Note – The trick option here was the first option. It's written in it the direction of flow of negative charge, although flow of negative charge too depicts flow of electric current but however the direction of current is exactly opposite to the direction of flow of electrons. Thus if it would have been written that opposite to the direction of flow of current that it would have been right.
