Explain why the resistance of ammeter is kept low.

Explain , why the input resistance of a transistor is low and output resistance is high.

Explain why the coils of the resistance box are wound over themselves?

Explain why resistance coils are usually double wound.

True or false The resistance of ammeteer is very high.

A galanometer has a resistance of 10 ohm. It gives maximum deflection for a current of 50 mA. Find the shunt resistance required to convert it into ammeter of range 2.5 A. What is the resistance of ammeter so constructed?

“The resistance of voltmeter is more than resistance of ammeter.’. Is the statement true or false ?
