Key Concepts

Ideal Transformer

An ideal transformer is a theoretical model of a transformer in which there is no loss of energy. It operates on the principle of electromagnetic induction, meaning that power input to the primary coil is completely transferred to the secondary coil without any energy losses. This model simplifies analysis by assuming perfect magnetic coupling and no resistive losses.

Turns Ratio

The turns ratio is the ratio of the number of windings (turns) in the primary coil to the number of windings in the secondary coil. This ratio is fundamental in determining how the voltage and current are transformed between the primary and secondary sides. For an ideal transformer, the voltage ratio directly equals the turns ratio, so the secondary voltage is proportional to the primary voltage multiplied by the ratio of the number of secondary turns to primary turns.

Voltage Transformation

Voltage transformation in a transformer is based on the relationship V_secondary/V_primary = N_secondary/N_primary. This means that if the secondary coil has more turns than the primary coil, the voltage in the secondary will be higher than in the primary, effectively stepping up the voltage. Conversely, if the secondary has fewer turns, the voltage is stepped down.
