A ammeter should have small resistance. Why?

Mark out the correct options (i) An ammeter should have small resistance (ii) An ammeter should have large resistance (iii) A voltage should have small resistance (iv) A voltage should have large resistance.

Which of the following statements are correct ? (1) Voltmeter should have high resistance. (2) Ammeter should have low resistance. (3) Voltmeter is placed in parallel across the conductor in a circuit. (4) Ammeter is placed in parallel across the conductor in a circuit.

Why should an ammeter have a low resistance and a high current carrying capacity?

While convertying galvanometer into an ammeter, how does the parallel low resistance (shunt) bring the required changes in the galvanometer?

Assertion : An ammeter is always connected in series whereas a voltmeter is connected in parallel. Reason : An ammeter is a low-resistance galvanometer while a voltmeter is high resistance galvanometer.

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.

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

A galvanometer of resistance 50Omega is converted into an ammeter by connecting a low resistance (shunt) of value 1Omega in parallel to the galvanometer, S. If full - scale deflection current of the galvanometer is 10 mA, then the maximum current that can be measured by the ammeter is -
