The video demonstrates the dangers of using an incorrect resistor in a circuit. The presenter shows what happens when a 15-ohm resistor rated for 0.25 watts is subjected to a 12-volt battery, resulting in a fire. The video then explains how to calculate the power going through a resistor and how to choose the right resistor for a circuit to avoid overheating and potential damage.
