The ratio of the shunt resistance and the resistance of a galvanometer is 1*499 . If the full scale deflection current of the galvanomter is 2mA , the range of ammeter is
The ratio of the shunt resistance and the resistance of a galvanometer is 1:499 . If the full scale deflection current of the galvanometer is 2mA , the range of the ammeter is
Statement I : If galvanometer is converted into an ammeter and milliammeter then the shunt resistance of ammeter is lower than that of milliammeter. Statement II : The shunt resistance must allow more current to pass through in case of ammeter than that of milliammeter
An ammeter of resistance 0*80Omega can measure current upto 1*0A . (a) What must be the value of shunt resistance to enable the ammeter to measure current upto 5*0A ? (b) What is the combined resistance of the ammeter and the shunt?
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?
Assertion : Resistance of an ammeter is less than the resistance of a milliammeter. Reason : Value of shunt required in case of ammeter is more than a milliammeter.
A moving coil galvnometer is converted into an ammeter reading up to 0.03 A by connecting a shunt of resistance r/4 . What is the maximum current which can be sent through this galvanometer if no shunt is used (here r=resistance of galvanometer)
