Primary Circuit:
Описание: The primary circuit refers to the part of an electrical system that receives electrical energy directly from a power source, such as a generator or a battery. It is responsible for supplying power to the rest of the circuitry. In an electrical transformer, the primary circuit consists of the primary winding, which is connected to the power source. The flow of current in the primary circuit induces a magnetic field, which is then transferred to the secondary circuit.
Пример: Calculate the current passing through the primary circuit of a transformer with a primary voltage of 120V and a primary resistance of 5 ohms.
Совет: When studying the primary circuit, it is important to understand the relationship between voltage, current, and resistance. Knowing Ohm"s Law (V = IR) can help you solve problems related to primary circuits.
Закрепляющее упражнение: A primary circuit has a voltage of 240V and a current of 6A. Determine the resistance of the primary circuit.
