A 3 phase transformer is a type of transformer that is designed to handle three-phase power distribution systems.

• Consists of three sets of primary and secondary windings

• Used in power distribution systems to step up or step down voltage in three-phase circuits

• Commonly used in industrial and commercial applications

• Examples include distribution transformers, power transformers, and autotransformers

A 2 phase transformer is a type of transformer that has two primary and two secondary windings.

• Consists of two primary windings and two secondary windings

• Used in certain industrial applications where a 3 phase transformer is not feasible

• Less common compared to single phase and 3 phase transformers

Kirchhoff's current law states that the total current entering a junction is equal to the total current leaving the junction.

• Total current entering a junction = Total current leaving the junction

• It is based on the principle of conservation of charge

• Used to analyze and solve electrical circuits

A semiconductor is a material that has electrical conductivity between a conductor and an insulator.

• Semiconductors have a conductivity between that of a conductor and an insulator

• They are used in electronic devices such as transistors, diodes, and integrated circuits

• Common semiconductor materials include silicon, germanium, and gallium arsenide

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.

• Current (I) = Voltage (V) / Resistance (R)

• It helps in calculating the current flowing through a circuit based on the voltage and resistance values.

• It is represented by the formula I = V/R.

• Ohm's Law is fundamental in understanding and analy
