Select the option that is true regarding the following two statements labeled Assertion (A) and Reason (R). Assertion (A): Whenever we measure an electrical signal, there are chances of over current which leads to overheating of the meter. In such cases, the meter can be protected by using a semiconductor diode of suitable rating. Reason (R): As soon as the diode is short-circuited, the meter current is diverted through the diode. As a result, the meter is being protected from excess heating.
