Ohm meter resistance
WebbAn ohmmeter is a device used to measure the resistance of a resistor. Using Ohm’s law, we know we can find the resistance of a circuit by dividing the voltage by the current: 𝑅 = 𝑉 𝐼. Let’s consider how we can find these values by attaching a … WebbOhm (Ω) Ohm (symbol Ω) is the electrical unit of resistance. The Ohm unit was named after George Simon Ohm. 1Ω = 1V / 1A = 1J ⋅ 1s / 1C 2. Table of resistance values of Ohm
