A voltmeter giving full scale deflection for of 100V. The

Direction: —A moving coil instrument gives full scale deflection for a current of 1 mA and voltage across if of 100 mv. In order to convert it to.

A voltmeter giving full scale deflection for of 100V. The required value of series resistance:

Here, full scale deflection = 100V
The series resistance can be connected as shown below—
voltage across, R_m = 1mA × 100 = 0·1V
So, voltage across

R_sh =	100 – 0·1	= 99·9 kΩ
	1mA
