Resistance in ohms
WebResistance (R) is a measure of how difficult it is for current to flow. Resistance is measured in units called ohms (Ω). The amount of. current. flowing in a circuit is affected by the … WebAboutTranscript. Ohm’s Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm’s Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you know the voltage of the battery in the circuit and how much resistance is in the circuit.
