How will you convert galvanometer which needs 50 mA for full scale deflection into a voltmeter reading upto 2.5 volts ? The resistance of the galvanometer is 10 ohms.

A galvanometer having a coil resistance 120 Omega shows full scale deflection for a current of 2.5 mA. How would you convert it into an ammeter of range 0 to 75A?

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

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]

A galvanometer gives full scale deflection with 0.2 mA. The resistance of its coil is 1000 ohms. How much shunt resistance is required to converted into an ammeter to measure currents upto a 2 amperers?

A galvanometer coil has a resistance of 10Omega and the meter shows full scale deflection for a current of 2.5 mA. How will you convery the metre into an ammeter of range 0 to 4A.

How will you convert:- C_2H_5BrrarrC_4H_(10)

A galvanometer has an internal resistance of 1.0 ohm. It gives maximum deflection for current of 50 mA. Show how it can be converted into (i) a voltmeter with a maximum reading a of 2.5 volts, (ii) an ammeter with a maximum reading of 2.5 A.

In a potentiometer experiment, it is found that no current passes through the galvanometer, when the terminals of a cell are connected across 50 cm of the potentiometer wire. If the cell is shunted by a resistance of 5 ohm, the balance point is found at 40 cm of the wire from the same end. Find the internal resistance of the cell.

A miliammeter of resistance 5 ohms gives a full scale deflection for a current of 15 mA. If the milliammeter is to be used to measure currents upto 1.5 A the size of the resistance that must be attached to the milliammeter is ?
