“How can we measure the resistance in an electronic component?”


Electronic structures such as resistors play a vital part in the workings of electrical devices through the use of resistance. However, how can we measure such a phenomena empirically? Well, let’s use our engineering mindset to figure it out. Firstly, we should be aware that it is possible to experimentally measure both the voltage and current between two points, and that the resistors of a circuit is equal to the voltage divided by the resistance (R = V/I). Therefore, it would be most rational to combine these two facts, and synthesize a most useful device known as the ohm-meter.
