Ohm’s Law is fundamental in electrical engineering and crucial for efficiently managing power stations. It states that the voltage (V) across an electrical circuit is directly proportional to the current (I) flowing through it, with the resistance (R) of the circuit being a constant factor in this relationship. The formula V = IR expresses this principle. In the context of power stations, Ohm’s Law helps technicians calculate the necessary voltage to overcome resistance in the transmission lines, ensuring optimal amperage is delivered for power generation and distribution tasks. This understanding aids in the efficient and safe operation of power systems, maximising the reliability of electricity delivery to end-users.
