PPT-1 DC Ammeter Galvanometer

is a PMMC instrument designed to be sensitive to extremely low current levels The simplest galvanometer is a very sensitive instrument with the type of centerzero scale The torque equation for a galvanometer is exactly as discussed in the previous section. Ammeter m easure current Voltmeters m easure voltage potential difference The tricky p rt is wir ng them into a circu it so th at they don t have m ch of an effect on the circu it o In the questions we do we assum t at we have perfect ammeters and v Current.
