What is the resistance of a galvanometer with a current 10 Ma?
[SOLVED] A galvanometer with resistance 100 Ω gives full scale deflection with a current of 10 mA . The value of shunt, in order to convert it into an ammeter of 10 ampere range, will be A galvanometer with resistance 100 Ω gives full scale deflection with a current of 10 mA.
Which galvanometer gives a full scale deflection of 10 amps?
A galvanometer having a coil resistance of 100 Ω gives a full scale deflection, when a current of 1 mA is passed through it. The value of the resistance, which can convert this galvanometer into ammeter giving a full scale deflection for a current of 10 A is:
How do you convert a galvanometer to an ammeter?
Galvanometer is a very sensitive instrument therefore it cannot measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low shunt resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. is passed through it.
What is the value of the shunt of a galvanometer?
The value of shunt, in order to convert it into an ammeter of 10 ampere range, will be A galvanometer with resistance 100 Ω gives full scale deflection with a current of 10 mA. The value of shunt, in order to convert it into an ammeter of 10 ampere range, will be
How do you convert a galvanometer to a voltmeter?
Let G be the resistance of a galvanometer and is equal to 10Ω. be the current through the galvanometer for full scale deflection and is 1 mA. Now, to convert galvanometer into an voltmeter a large resistance R should be connected in series with galvanometer.
What is the working principle of moving coil galvanometer?
The series combination of a variable resistance R, one 100Ω resistor and a moving coil galvanometer is connected to a mobile phone charger having negligible internal resistance. The zero of the galvanometer lies at the centre and the pointer can move 30divisions full scale on either side depending on the direction of current.
