Round 1 - Technical 

(2 Questions)

  • Q1. What is transformer?
  • Ans. 

    A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

    • Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

    • They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

    • When an AC voltage is applied to the primary coil, it creates a magne...

  • Q2. What is power fectore
  • Ans. 

    Power factor is the ratio of real power to apparent power in an AC circuit.

    • It is a measure of how efficiently power is being used in a circuit.

    • A power factor of 1 means all the power is being used effectively, while a power factor of 0 means no power is being used.

    • It is important to have a high power factor to avoid wasting energy and reduce electricity bills.

    • Power factor correction techniques can be used to improve po...

Round 1 - Technical 

(2 Questions)

  • Q1. What is voltage
  • Ans. 

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

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

    • It is measured in volts (V) and represents the potential energy per unit charge.

    • Voltage can be positive or negative, depending on the direction of current flow.

    • Higher voltage means more potential energy and can result in greater current flow.

    • Examp...

  • Q2. What is current
  • Ans. 

    Current is the flow of electric charge in a circuit.

    • 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.

  • Answered by AI
Round 2 - Technical 

(1 Question)

  • Q1. What isOHM's law
  • Ans. 

    Ohm's law states that the current flowing through a conductor is directly proportional to the voltage 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.

    • For example, if a circuit has a vol...

  • Q1. Explain basic components in Electronics
  • Ans. 

    Basic components in Electronics include resistors, capacitors, inductors, diodes, transistors, and integrated circuits.

    • Resistors: Control the flow of electric current in a circuit.

    • Capacitors: Store and release electrical energy.

    • Inductors: Store energy in a magnetic field.

    • Diodes: Allow current to flow in one direction only.

    • Transistors: Amplify or switch electronic signals.

    • Integrated Circuits: Combine multiple components

  • Answered by AI
  • Q2. What is power and its units
  • Ans. 

    Power is the rate at which work is done or energy is transferred. Its units are watts (W) in the International System of Units.

    • Power is the amount of energy transferred or converted per unit time.

    • The SI unit of power is the watt (W), which is equal to one joule per second.

    • Other common units of power include horsepower (hp) and kilowatt (kW).

    • Power can be calculated using the formula: Power = Work / Time
