Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion : For measuring resistance of an ionic solution an AC source is used.
Reason : Concentration of ionic solution will change if DC source is used.
For measuring resistance of an ionic solution an AC (Alternating current) source is used because concentration of ionic solution will change if DC (Direct current) source is used. DC current can change the composition of the ionic solution.
