What is Considered Resistance in Electricity? How Can Resistance be Measured?

Resistance is the repulsion of current within an electrical circuit. The electric meterresistance helps one to make sense of the way voltage and current work. Voltage is the amount of electrical pressure, while current is the flow of electricity. Resistance, discovered in 1827 by Georg Simon Ohm, is actually the ratio between voltage and current. Ohms law states, “The voltage between any two points in a conductor changes directly as the current between the two points, given the temperature remains the same and does not change.” One can measure and determine the resistance by using Ohm’s formula:


R stands for resistance (measured in ohms), while V is the voltage (measured in volts) and I is the current going through the object (measured in amperes).
