Assertion is true but the reason is false.
Both assertion and reason are false.
Assertion is false but reason is true.
उत्तर
Both assertion and reason are true and the reason is the correct explanation of assertion. (ii) Both assertion.
Explanation:
Alternating current is used in the measurement of resistance of electrolyte solution because concentration changes with DC current due to electrolysis.
