Nokia Diploma Electrical Engineer Interview Questions and Answers

An electrical machine is a device that converts electrical energy into mechanical energy or vice versa. Ohm's Law relates voltage, current, and resistance. KVL and KCL are laws used in circuit analysis.

• Electrical machine is a device that converts electrical energy into mechanical energy or vice versa

• 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 conduct...read more

A clamp meter is a tool used to measure electrical current without the need to disconnect the circuit, while a teco meter is used to measure the speed of an electric motor. Capacitance is the ability of a component to store electrical charge.

• Clamp meter is used to measure electrical current in a conductor without the need for direct contact.

• Teco meter is used to measure the speed of an electric motor.

• Capacitance is the ability of a component to store electrical charge, measur...read more

Renewable energy sources are sources of energy that are replenished naturally, such as sunlight, wind, and water. Non-renewable energy sources are sources that cannot be easily replenished, such as fossil fuels.

• Renewable energy sources include solar power, wind power, hydropower, and geothermal energy

• Non-renewable energy sources include coal, oil, and natural gas

• Renewable energy is sustainable and environmentally friendly, while non-renewable energy contributes to pollution a...read more

Flaming Lept Hand Rule is a rule used in electrical engineering to determine the direction of current flow in a conductor.

• Flaming Lept Hand Rule is used to determine the direction of current flow in a conductor when the direction of magnetic field and motion of conductor are known.

• It states that if the thumb, index finger, and middle finger of the right hand are extended in such a way that the thumb points in the direction of motion, index finger points in the direction of ma...read more
