Which instrument is best to use to check whether the source of supply is AC or DC?
The simplest is a voltmeter; the best is an oscilloscope.
All modern voltmeters have an AC/DC selector switch. When set to AC and measuring a DC source, the reading will be 0; when set to DC and measuring an AC source, the reading will be 0 or varying wildly.
An oscilloscope will show you a flat line for a DC source, and a sinusoidal curve centered at 0 for an AC source.
