Chris · Answer 1 · 2024-03-16T11:37:42+0000

The accurate choice is (b) Half scale deflection in the ammeter

In the realm of explanation: Given Vin=1v ,R1=10+2kΩ ≅2kΩ

Io = Vin/R1= 1v/2kΩ =0.5mA. This means that 2v causes half scale deflection of the ammeter.

In the diagram given below, determine the deflection of the ammeter with a full scale deflection of 1mA when the switch is at X2kΩ. Consider resistance of the offset voltage compensating network to be 10Ω.
