## Homework Statement

Meter in the circuit shown has a linear scale that has not been calibrated and the scale reading is 20 . When another resistor of resistance 2000 ohm is connected across XY . What is the scale reading of the meter

## Homework Equations

## The Attempt at a Solution

Without the 2000 ohm resistor , I= 1.5 /(2995 + 50) , I = 0.0005

the reading given by the ammeter is 40600 times of the actual current .

now with the resistor , I = 1.5/(2995 + 50+2000) , I = 0.0003

the reading by the ammater will be 0.0003 x 40600 = 12

but the answer given is 25
