Convert a moving coil galvanometer into a ammeter.

Convert a moving coil galvanometer into a voltmeter.

How can you convert a galvanometer into an ammeter ? Explain with diagrams.

State two factors on which the sensitivity of a moving coil galvanometer depends.

What is the basci principle of a moving coil galvanometer? Derive an expression for current flowing through the galvanometer in terms of steady angular deflection of its coil. Define voltage. Sensitivity of the galvanometer. What is a convenient way to increase its sensitivity?

A galvanometer having a resistance of 50Ω gives a full scale deflection for a current of 0.05 A. The length in meter of a resistance wire of area of cross section 3×10^−3 cm^2 that can be used to convert the galvanometer into an ammeter which can read a maximum of 5A current is [specific resistance of the wire =5×10^−7 Ωm]
