SUMMARY
The discussion focuses on verifying the current draw of a 12V car headlight, specified by the manufacturer to be 6A. Participants clarify the distinction between voltmeters and ammeters, emphasizing that a voltmeter cannot measure current directly. A suggestion is made to use a 0.1 Ohm shunt resistor to convert a voltmeter into an ammeter for accurate current measurement. The importance of understanding circuit junctions and their impact on current and potential difference (pd) is also highlighted.
