From ohm's law current is
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 says that if you take any material, like let's say, windings of a wire and if we apply a potential difference across the ends of that, so let's say the potential difference …
