The difference between DC ammeter and AC ammeter
It is a wide-angle ammeter that is embedded and installed on ships or other occasions of electrical equipment to measure AC voltage and AC current with a rated operating frequency of 50Hz and 60Hz.
The difference between DC and AC
DC ammeters and AC ammeters are very different, and measurements cannot be exchanged, and there is no way to exchange measurements. For high-current ammeters, a DC ammeter is actually just a 75 millivolt DC voltmeter (which measures the millivolts on the shunt. volts), and the internal resistance of the AC ammeter is very small (the measurement is the short-circuit current of the secondary of the transformer), which is a short circuit for the circuit, and the current can allow AC 5 amperes to flow.
