In a step-up transformer, the primary coil has fewer turns than the secondary coil.

The turns ratio of a transformer determines the voltage transformation ratio.

In a step-down transformer, the current increases while the voltage decreases.

In a step-down transformer, the current in the secondary winding increases as the voltage decreases, maintaining power balance.

If the load resistance decreases, the current in the secondary winding of a transformer increases.

Transformers operate on the principle of electromagnetic induction.

Increasing the number of turns in the primary winding increases the output voltage in a step-up transformer.

An ideal transformer has an efficiency of 100%, meaning no energy is lost.

One of the main disadvantages of using a transformer is its size and weight, especially for high power applications.

The primary winding of a transformer is connected to a power source, which provides the input voltage.

Transformers operate on the principle of electromagnetic induction, where a changing magnetic field induces voltage in a coil.

The relationship between primary and secondary voltage is given by V1/V2 = N1/N2, where N is the number of turns.

The magnetic field in a transformer is crucial for inducing voltage in the secondary winding through electromagnetic induction.

Iron loss refers to the energy lost in a transformer due to heat in the core material.

Silicon steel is commonly used as the core material in transformers due to its magnetic properties.
