What are Vault Meters and Ammeters ?

1 Answer

Answer :

: Ammeter is used to measure current flow and Vault meter is used to measure voltage. These two measuring instruments are usually in one place and the two are often called multimeters. A multimeter usually has a dial and this dial can be rotated to measure different levels of voltage or current. Since our household voltage is AC, all multimeters can measure AC or DC voltage and current. Today's multimeters can measure many things, not just voltage and current.
