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.
