Find the expression for the shunt resistance in a circuit where galvanometer is converted into ammeter

Write an expression for resistance required to con vert the moving coil galvanometer in to voltmeter.

Find the equivalent resistance of the above circuit.

Find the effective resistance of the circuit given below:

Resistance are used to reduce the current flow in a circuit. Resistance can be connected in series and parallel to obtain the required value of resistance. Derive an expression for the effective resistance when three resistors are connected in parallel.

A galvanometer is used to detect current in a circuit. How will you convert a galvanometer Into an ammeter
