Question

Which one of the following situations represents an electric current 'to the right'?

a)Protons moving to the left.

b)Protons moving to the right.   

c)Electrons moving to the right.

Answer 1

Since direction of current is opposite direction of motion of electron or similar direction to motion of proton.

given, option - a.)

direction of motion of proton = left

So, direction of electric current = left

option - b.)

direction of motion of proton = right

So, direction of electric current = right

option - c.)

direction of motion of electron = right

So, direction of electric current = left

therefore,option b.) represents an electric current 'to the right'.
