A moving coil galvanometer can measure a current of `10^(-6)` A. What is the resistance of the shunt required if it is to measure 1A ?

How can galvanometer be converted to a voltmeter ? Why is the series resistance greater that the galvanometer resistance ? A moving coil galvanometer of resistance 5Omega can measure a current of 15mA. What is the series resistance required if it is to measure 1.5 V ?

An ammeter of resistance 1 W can measure current upto 1.0 A. (i) What must be the value of the shunt resistance to enable the ammeter to measure upto 5.0 A? (ii) What is the combined resistance of the ammeter and the shunt?

An ammeter of resistance 1 Ohm can measure current upto 1.0 A. (i) What must be the value of the shunt resistance to enable the ammeter to measure upto 5.0 A? (ii) What is the combined resistance of the ammeter and the shunt?

An ammeter of resistance of 0.8 Omega can measure current upto 2A. What must be the shunt resistance to enable the ammeter to measure currents up to 10 A ?

Why is it that while using a moving coil galvanometer as a voltmeter, a high resistance in series is required whereas in an ammeter a shunt is used?
