MHT CET Physics question
An ammeter gives full deflection when a current of 2 A flows through it. The resistance of the ammeter is 12 ohm. If the same ammeter is to be used for measuring a maximum current of 5 A, then the ammeter must be connected with a resistance of
Answer: (C)
Solution
A larger range needs a parallel shunt ; series resistances (a, b)
