When turning on a light, what scientific condition are you causing to make the lights work?

Explanation:

A professor of chemistry at COC's Paraíso unit, in São Paulo, Marcelo Polachini makes an experiment using a lamp to explain the characteristics of the conduction of electrical current.

“Electrolytes are substances that conduct electrical current and non-electrolytes do not conduct electrIn the experiment, the professor introduces the electrodes of an apparatus with a lamp in different ways to see if there is electrical current conduction, which will allow the lamp to light.

"For the lamp to light, some conditions need to be met: the substances with which the electrodes will have contact must present electrical charges and mobility, such as solid and liquid metals, graphite in solid form and ionic compounds (metal + non-metal) and acids in solution .”

According to the professor, the strength of the acid will determine the intensity of the lamp's brightness.ical current,” he explains.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
