Torrent Cables Diploma Electrical Engineer Interview Questions and Answers

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.

• Current flows from high potential to low potential.

• There are two types of current - AC (Alternating Current) and DC (Direct Current).

• Examples of current sources include batteries, generators, and power plants.

Resistance is the opposition to the flow of electric current in a circuit.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a conductor.

• Higher resistance leads to lower current flow in a circuit.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• Examples of resistors include light bulbs, heating elements, and electronic

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.

• Ohm's Law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It was formulated by German...read more

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

• Voltage is the potential difference between two points in an electrical circuit

• It is measured in volts (V)

• Voltage is responsible for the flow of current in a circuit

• Higher voltage means more potential energy available to move electrons

• Examples: 120V in household outlets, 12V in car batteries

Drift velocity is the average velocity of charge carriers in a particular direction under the influence of an electric field.

• Drift velocity is a result of the electric field applied to a conductor.

• It is typically very small, on the order of millimeters per second.

• Drift velocity is influenced by the material of the conductor and the strength of the electric field.

• It is an important concept in understanding current flow

An analog signal is a continuous signal that represents information using a continuous range of values.

• Analog signals can take on any value within a continuous range.

• Examples of analog signals include voltage, current, and sound waves.

• Analog signals are used in many electronic devices such as radios and televisions.

Resistance is the opposition to the flow of electric current in a circuit.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a material.

• Higher resistance leads to lower current flow in a circuit.

• Resistance can be affected by factors like material, length, and temperature.

• Example: A light bulb has resistance that converts electrical energy into light and heat.

Inductance is the property of an electrical circuit that opposes changes in current flow.

• Inductance is measured in Henry (H)

• It is caused by the magnetic field generated when current flows through a conductor

• Inductors are components that are designed to have a specific inductance value

• Inductance is used in filters, transformers, and motors

Capacitance is the ability of a system to store an electric charge.

• Capacitance is measured in Farads (F).

• It is the ratio of the electric charge stored on a conductor to the potential difference across it.

• Capacitors are electronic components that are designed to store and release electrical energy.

• Capacitance is used in various applications such as filtering, energy storage, and timing circuits.

Electricity can be produced through various methods such as burning fossil fuels, harnessing renewable energy sources like wind and solar, or using nuclear reactions.

• Burning fossil fuels like coal, oil, and natural gas in power plants to generate steam that drives turbines connected to generators.

• Harnessing renewable energy sources like wind turbines to convert kinetic energy into electricity.

• Using solar panels to conv...read more
