The resistance of ammeter is very high as compared to voltmeter .

The resistance of ideal voltmeter is:

True or false The resistance of ammeteer is very high.

Explain why the resistance of ammeter is kept low.

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
