The resistance of an ammeter is `13 Omega` and its scale is graduated fro a current upto `100 A`. After an additional shunt has been connected to this ammeter it becomes possible to measure currents upto `750 A` by this meter. The value of shunt resistance is

The resistance of an ammetre is 13 Omega and its scaleis graduated for a current upto 100 amps.After and additional shunt has been connected to this ammeter it becomes possible to measure currents upto 750 amperes by this meter.The value of shunt resistance is:

To increase the range of an ammeter the value of the 'shunt' resistance has to be

A galvanomter of resistance 100 Omega gives full scale deflection for a current of 10 mA. What is the value of the shunt to be used to convert it into an ammeter which can measure current up to 10A ?

The resistance of a galvanometer is 100Omega . A shunt of 5 Omega is connected to it to convert it into an ammeter. The internal resistance of the ammeter is

An ammeter of resistance 0.80 Omega can measure current upto 1.0 A. (i) What must be the value of shunt resistance to enable the ammeter to measure current upto 5.0 A ? (ii) What is the combined resistance of the ammeter and the shunt ?

An ammeter of resistance 0.6Omega can measure current upto 1.0 A. Calculate (i) The shunt resistance required to enable the ammeter to measure current upto 5.0 A (ii) The combined resistance of the ammeter and the shunt.
