Kanohar Electricals Electrical Engineer Interview Questions, Process, and Tips

Current and voltage are two key parameters in electrical engineering that determine power consumption.

• Current is the flow of electric charge in a circuit, measured in Amperes (A).

• Voltage is the electrical potential difference between two points in a circuit, measured in Volts (V).

• Power is the rate at which energy is transferred in a circuit, calculated as the product of current and voltage (P = I * V).

• Higher current or...read more

Transformers are devices used to transfer electrical energy between two or more circuits through electromagnetic induction, while losses refer to the energy dissipated in the transformer due to various factors.

• Transformers are used to step up or step down voltage levels in electrical systems.

• Losses in transformers can be categorized as copper losses (due to resistance in windings) and core losses (due to hysteresis and...read more

Resistance and capacitor are two different components in electrical circuits with distinct functions.

• Resistance limits the flow of current in a circuit, while a capacitor stores and releases electrical energy.

• Resistance is measured in ohms (Ω) and depends on the material and dimensions of the component.

• Capacitance is measured in farads (F) and depends on the area and distance between the plates of the capacitor.

• Resista...read more

Electron is a negatively charged subatomic particle, proton is a positively charged subatomic particle, and neutron is a neutral subatomic particle.

• Electron is a subatomic particle with a negative charge.

• Proton is a subatomic particle with a positive charge.

• Neutron is a subatomic particle with no charge.

• Electrons are found in shells around the nucleus of an atom.

• Protons and neutrons are found in the nucleus of an atom.

• ...read more

AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.

• AC stands for alternating current, which changes direction periodically

• DC stands for direct current, which flows in one direction

• AC is commonly used in household electrical outlets, while DC is used in batteries and electronic devices

• AC can be easily converted to DC using a rectifier

• Examples of AC sources in...read more
