Assertion (A): Galvanometer to ammeter conversion takes place by connecting a low value resistance in parallel with it. |
Reason (R): The low value resistance increases the effective resistance and protects the galvanometer. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: C
Solution :
Option [c] is correct |
Explanation: Galvanometer to ammeter conversion takes place by connecting a low value resistance known as "shunt" in parallel with it. The assertion is true. |
When two resistors are connected in parallel then the effective resistance becomes lower than the lowest value of the two resistors. |
Hence the reason is false. |
