Part 5/8:
The experimenter then approaches the critical moment of attempting a spark jump—an indicator of high voltage—and aims to produce a visible arc by connecting the circuits. As the connection is made, a spark appears briefly, accompanied by a flash of light on the LED. During this process, the voltage meter momentarily drops sharply to zero volts, illustrating how sudden discharges can temporarily disturb the circuit's readings before quickly bouncing back up.
