Vedclass · Answer

(D) galvanometer is a sensitive device designed to detect small currents. $1$. If the current flowing through the circuit is less than the current required for full-scale deflection $(I_g)$,the needle will not reach the end of the scale. $2$. $A$ galvanometer has a finite internal resistance $(G)$. If it is connected in series with a high resistance $(R)$,the total resistance of the circuit increases significantly,reducing the current according to Ohm's Law $(I = V / (R + G))$. $3$. Consequently,if the circuit parameters are not matched to the galvanometer's sensitivity,it will not show full-scale deflection. Therefore,all the mentioned factors can contribute to this observation.
