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

• The hydraulic cylinders i...read more

Crane wheel wear is caused by factors such as overloading, misalignment, lack of lubrication, and poor maintenance.

• Overloading the crane beyond its capacity can cause excessive wear on the wheels.

• Misalignment of the crane wheels can lead to uneven wear and premature failure.

• Lack of proper lubrication can increase friction and wear on the wheels.

• Poor maintenance practices, such as not regularly inspecting and replacing

Limits used in EOT crane include overload limit, travel limit, and height limit.

• Overload limit prevents the crane from lifting loads beyond its capacity

• Travel limit restricts the crane's movement within a specified range

• Height limit ensures the crane does not exceed the maximum height for safe operation
