STUDY OF VOLTAGE AND CURRENT MEASUREMENT USING MULTIMETER

3- STUDY OF VOLTAGE AND CURRENT MEASUREMENT USING MULTIMETER

Aim:

To measure voltage and current using multimeter.

APPARATUS REQUIRED:

                   Multi meter

THEORY:

          Multi meter is used to measure voltage, current and resistance. Therefore it is called AVO Meter. For measuring AC voltage if the range selected switch at the AC select the proper multiplier range. The various voltage ranges are 10V, 55V, 250V, 1000V always start from highest scale.

PROCEDURE:

1. DC is polarity sensitive; it required to connect with proper terminals. The multi meter leads are colour coded red and black.
2. Connect the red lead to the positive and black to negative.
3. While taking measurement on receiver, click the black lead to the chassis red lead to the point. Where measurement are to be noted. For DC current measurement procedure is same and DC voltage measurement and DC current measurement multi meter is connected in series. If the range selected switch at the DC current range.
4. The various DC current ranges are 10Ma, 100Ma, 250Ma, and 1A on the multi meter.
5. Check the main voltage of domestic supply with the help of multi meter; It should be 220 – 230V.

RESULT: In the given circuit the voltage and current are studied in the given multi meter.
