The main key difference between DC voltmeter and AC voltmeter is that the DC voltmeter measures the peak value while in AC voltmeter measure the RMS value of the AC voltage. So let us discuss with the main key difference between DC voltmeter and AC voltmeter to better understand this topic.
The main key difference between DC voltmeter and AC voltmeter:
- The measuring quality is the crucial factor that differentiates DC voltmeter and AC voltmeter. The DC voltmeter measures the DC voltage but the AC voltmeter measures the AC voltage.
- The DC voltmeter measures the peak value of DC voltage but the AC voltmeter measures the RMS value of the AC voltage.
- DC voltmeter does do not use a rectifier before a multistage amplifier whereas the AC voltmeter measures the RMS value of the AC voltage.
