Resistance of ammeter. A shunted PMMC galvanometer is called a PMMC ammeter. Clearly, the value of ammeter resistance will be less than S. Since the value of S is very small, the ammeter resistanc will also be very low. Thus shunt has not only extended the current range but it has also lowered the resistance of the ammeter a desirable requirement for an ammeter | |
