Ohms is the unit of measurement for electrical resistance in a circuit, represented by the symbol 'Ω'. This concept is essential for understanding how electricity flows through various devices, as it helps quantify how much opposition a material presents to the current. The relationship between voltage, current, and resistance can be expressed using Ohm's Law, which states that voltage equals current times resistance (V = IR). Understanding ohms is crucial for evaluating the performance and safety of electrical devices.
