The ratio of a transformer refers to the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.

• The ratio of a transformer determines the voltage transformation between the primary and secondary windings.

• It is calculated by dividing the number of turns in the primary winding by the number of turns in the secondary winding.

• For example, if a transformer has 100 turns in the pr...read more

The type of bridge is a crucial factor in engineering and construction. It determines the load-bearing capacity and structural design of the bridge.

• There are several types of bridges, including beam bridges, arch bridges, suspension bridges, cable-stayed bridges, and truss bridges.

• Beam bridges are the simplest type, consisting of a horizontal beam supported by piers or abutments at each end.

• Arch bridges have a curved d...read more

A synchronous generator is a type of generator that produces alternating current (AC) with a constant frequency.

• Synchronous generators are commonly used in power plants to generate electricity.

• They operate at a constant speed and are synchronized with the grid frequency.

• The rotor of a synchronous generator is excited by a DC current to create a rotating magnetic field.

• The stator windings of the generator then produce A...read more
