Ammeters and Voltmeters: Ideal and Non-Ideal - IB Physics
Ammeters measure current and voltmeters measure voltage. Ideal ammeters and voltmeters do not change any of the properties of the circuit they are measuring, while non-ideal ammeters and voltmeters do change the properties of the circuit. Ideally, we would want our measurement devices to NOT change the nature of what we're measuring. In this video I explain the properties that cause ammeters and voltmeters to be ideal and non-ideal.
