WebNov 5, 2024 · Using an ohmmeter, a student measures the resistance between various points on his body. He finds that the resistance between two points on the same finger is about the same as the resistance between two points on opposite hands—both are several hundred thousand ohms. WebOhm’s law states that the electrical current through a conductor is proportional to the potential difference across it. Furthermore, the electrical resistance of the conductor is constant. This leads to the mathematical equation: R = V I R = V I. where R the resistance in ohms (Ω), V the voltage in volts (V), and I is the current in amperes (A).
