Question

Define current sensitivity and voltage sensitivity of a galvanometer.Increasing the current

Answer 1

Answer:

Refer to the attachment given

Answer 2

Current sensitivity of a galvanometer:

*It is defined as the deflection producedwhen unit current passes through the galvanometer.

*A galvanometer is said to be sensitive if it produces large deflection for a small current.

Voltage sensitivity of a galvanometer:

*It is defined as the deflection per unit voltage.

*Shunt is a low resistanceconnected. in parallel with the galvanometer.

*Ideal ammeter has zero resistance.

*Ideal voltmeter offers infinite resistance to current.
