Result
1. The D.C./A.C. voltage, D.C. current and resistance have been measured by using a multimeter.
2. The A.C./D.C. voltage measured by multimeter is same as that of voltage marked on A.C./D.C. source.
3. The values of resistance measured by multimeter is same as that measured by colour coding.
