To measure d current in any circuit we hav to connect d galvanometer in series wit tht circuit now bcoz of resistance of galvanometer it gives d wrong value of current i.e low than actual value so we connect a shunt in parallel so d resistance of galvanometer is reducedAlso a small current gives a full scale deflectionnow my question isAgar apane 10 amp current bheja to a circuit without shunt then assume that it gives d reading 8 ampPar jab apan shunt circuit me lagayge to galvanometer ka resistance kam hoga par shunt me se bhi to current pass hoga aur reading wrong ayegi naOne more thing if we connect a shunt in parallel then more current will pass thro galvanometer then it will give full scale deflectionthen what is d use of shunt?????And Guys what are d types of resistance???
