. Can a multimeter be used as substitute of all the ammeters and voltmeters? If so, why?

Yes, a multimeter can be used as a substitute for both ammeters and voltmeters. Here’s why:

1. Versatility: A multimeter combines the functions of a voltmeter, ammeter, and often ohmmeter in one device. This allows it to measure voltage, current, and resistance.

2. Functionality:

   • A multimeter measures voltage by connecting its probes across the component or circuit element. This is the same method used by voltmeters.
   • To measure current, a multimeter can be placed in series with the circuit, similar to an ammeter.

3. Digital Display: Most modern multimeters feature a digital display that provides clear readings for voltage, current, and resistance, making it user-friendly and accurate.

4. Adjustable Range: Many multimeters have adjustable ranges for both voltage and current measurements, which can be more convenient than using different devices for each measurement.

However, it is essential to note that while multimeters can substitute for ammeters and voltmeters, they may not always provide the same level of precision or have the same current and voltage limits as dedicated devices. Always ensure that the multimeter is properly set to the appropriate mode and range for the measurement being taken.
