Verifying Series Resistance with a Meter Bridge

Physics isn't magic, it's just math that you can actually touch. We used a meter

bridge to prove that the law of series resistance is legit. You take two resistor

coils, measure them separately, and then chain them together. The whole experiment

relies on sliding a jockey across a wire until the galvanometer hits exactly zero,

balancing the Wheatstone network. It feels tedious, but here is the crazy part.

When we crunched the numbers, our experimental data matched the theoretical addition

perfectly. It turns out when you connect resistors in a series, the resistance really

does just add up.
