"Increasing the current sensitivity of a galvanometer may not increase its voltage sensitivity". Justify this statement .

Answer»

Solution :Current sensitivity=`(NAB)/K`, Voltage sensitivity= `(NAB)/(KR)`
Current sensitivity can be increased by INCREASING the number of turns. But it increases the RESISTANCE of the coil (for a given AREA A). So the voltage sensitivity REMAINS the same.
