How does an electrical transformer work?
An electrical transformer works on the principle of electromagnetic induction. It consists of two or more coils of wire (primary and secondary) wound around a common core. When alternating current (AC) flows through the primary coil, it creates a changing magnetic field in the core. This changing magnetic field induces a voltage in the secondary coil.
The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines how the voltage is transformed.
How does a transformer work?
A transformer works by transferring electrical energy between two or more circuits by electromagnetic induction. The primary coil receives electrical energy, which generates a magnetic field in the core. This magnetic field induces a voltage in the secondary coil, where electrical energy is transferred.
The voltage level in the secondary coil depends on the turns ratio between the primary and secondary coils.
A transformer changes the voltage by adjusting the turns ratio between its primary and secondary coils. If the secondary coil has more turns than the primary coil, the transformer increases the voltage. Conversely, if the secondary coil has fewer turns than the primary coil, the transformer lowers the voltage.
This change in voltage is achieved using the principles of electromagnetic induction and the transformation ratio.
How does a transformer change voltage?
The current in a transformer depends on its design and the load connected to it. The transformer operates with alternating current (AC) and the primary and secondary currents are linked by the transformation ratio. If a transformer increases the voltage, the current in the secondary coil will be less than the current in the primary coil, and vice versa.
Power (voltage times current) remains approximately constant, minus losses.
A transformer increases voltage when the secondary coil has more turns than the primary coil. This configuration increases the voltage from the primary side to the secondary side.
The increase in voltage is proportional to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil, allowing the transformer to provide a higher voltage on the secondary side compared to the primary input.
