UNITEK POWER SOLUTIONS Junior Engineer Interview Questions and Answers for Experienced

Current is the flow of electric charge through a conductor.

• Current is measured in Amperes (A).

• It is the rate of flow of electric charge past a point in a circuit.

• Current can be either direct current (DC) or alternating current (AC).

• In a series circuit, the current remains the same throughout.

• Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance.

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

• Voltage is the force that pushes electric current through a circuit.

• It is measured in volts (V).

• Voltage is the potential difference between two points in a circuit.

• Higher voltage means more potential energy available to move electrons.

• Example: A battery with a voltage of 1.5V can power a small flashlight.

Electrical machines are devices that convert electrical energy into mechanical energy or vice versa.

• Types of electrical machines include motors (convert electrical energy to mechanical energy) and generators (convert mechanical energy to electrical energy).

• Common examples of electrical machines include induction motors, synchronous motors, DC motors, and transformers.

• Electrical machines play a crucial role in various i...read more

A synchronous generator is a device that converts mechanical energy into electrical energy with a constant speed of rotation.

• Consists of a rotor and a stator

• Produces AC power at a fixed frequency

• Used in power plants, wind turbines, and hydroelectric plants

Clogging is the blockage or obstruction of a pipe, tube, or passage by foreign material or waste.

• Clogging occurs when foreign material or waste accumulates and restricts the flow of fluids or gases.

• Common examples of clogging include hair in a shower drain, food particles in a kitchen sink drain, or dirt in a vacuum cleaner filter.

• Clogging can lead to reduced efficiency, malfunction, or damage in various systems such a...read more

The type of electrical machine used in wind turbines for power generation is the induction generator.

• Induction generator is commonly used in wind turbines due to its simplicity, reliability, and low maintenance requirements.

• It operates on the principle of electromagnetic induction to convert mechanical energy from the wind into electrical power.

• Induction generators do not require a separate power source for excitation,...read more
