Q5 of 22 Page 344

Should the resistance of an ammeter be low or high? Give reason.

Resistance of an ammeter should be low. If the resistance is more the current will be less. If the ammeter has zero resistance then we will get the exact current but it is not possible as every material in the every material have some resistance. So the resistance of the ammeter should be low.
