It is necessary to use a milliammeter with a 20mA scale as an ammeter for measuring currents upto 5A.
Calculate the resistance of the shunt if the internal resistance of the milliammeter is 8 Ohm.
The deflection in a galvanometer falls from 50 divisions to 10 divisions when a 12 Ohm shunt is applied.
Calculate the galvanometer resistance.
An I deal voltmeter has ------------------ resistance
Can we decrease the range of a given ammeter
Which is NOT a Moving Coil Galvanometer?
A galvanometer has a reistance of 5 Ohm and a full scale deflection is produced by 15 mA.
What resistance must be connectd to enable the galvaometer to ra 1.5A
