Smaller Battery = BRIGHTER Light?!!! - #SHORTS

This is Quint BUILDs entry for the #VeritasiumContest. Contest details: https://www.veritasium.com/contest In case it wasn't clear from the video, the smaller battery has a higher voltage, but that just means the bulb will "eat" through it even faster than if it were the same voltage as the larger battery. Key takeaways: - Higher voltage (V) pushes more current (I) thru the same bulb (V=IR or I=V/R, Ohm's law). - The smaller battery is a stack of many tiny sandwiches (higher voltage) which gets "eaten" very quickly. - Current always completes a circuit to ground (bulb was pooping ground symbols). Not covered: - Battery capacity is rated in amp-hours, but this is not a measure of power or energy. - Power=Volts x Current (watts), Energy=Power x Time (watt-hours) - Battery chemistry (Alkaline vs. Nickel or Lithium) affects battery capacity significantly. - Cheap battery brands often lie about capacity, so buyer beware! - Batteries often don't include rated capacity on the label. Rather they publish runtime charts under various conditions on their websites. Derek is a man after my own heart, exploring and sharing, even when the results are controversial. What a cool way to capitalize on his bet, generating a surge of short STEM videos online! What do you think, should I do more videos like this one? It was a lot of work cramming that much information into 60 seconds but I enjoyed every moment!
