Question

The internal resistance of the milliammeter must be very low for

Select one:

a. High sensitivity

b. High accuracy

c. Maximum voltage drop across the meter

d. Minimum effect on the current in the circuit

​

Answer 1

Answer:

A high value of internal resistance will vary the current considerably in a milli-ammeter as the current is in milli range. So the internal resistance of a milli-ammeter must be very low.
