Question

Assertion (A): To increase the range of an ammeter, we must connect a suitable high resistance in series to it.

Reason (R): The ammeter with increased range should have high resistance.

Select the most appropriate answer from the options given below:

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false and R is also false.

Answer 1

A is false and R is also false.

Explanation:

To increase the range of an ammeter, suitable low R (or shunt) should be connected in parallel to it. 
The ammeter with increased range has low resistance.
