Round 1 - Technical 

(11 Questions)

  • Q1. What is transformer
  • Ans. 

    A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

    • Consists of two coils of wire (primary and secondary) wrapped around a core

    • Primary coil receives electrical energy and creates a magnetic field

    • Magnetic field induces a voltage in the secondary coil, transferring energy

    • Used to step up or step down voltage in power distribution systems

  • Answered by AI
  • Q2. What is current transformer?
  • Ans. 

    A current transformer is a type of instrument transformer used to measure alternating current.

    • Used to step down high currents to a lower, more manageable level for measurement

    • Consists of a primary winding and a secondary winding

    • Secondary winding is connected to measuring instruments or protective relays

    • Provides accurate current measurement without affecting the main circuit

  • Answered by AI
  • Q3. What is the difference between ideal transformer and practical transformer?
  • Ans. 

    Ideal transformer is theoretical with no losses, while practical transformer has losses due to resistance, leakage flux, etc.

    • Ideal transformer has no losses, while practical transformer has losses due to resistance, leakage flux, hysteresis, and eddy currents

    • Ideal transformer has infinite efficiency, while practical transformer has efficiency less than 100%

    • Ideal transformer has no voltage drop, while practical transfor...

  • Answered by AI
  • Q4. What is voltage?
  • Ans. 

    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).

    • Higher voltage means more potential energy for electrons to flow.

    • Voltage can be compared to water pressure in a pipe - higher pressure (voltage) means faster flow (current).

  • Answered by AI
  • Q5. What is turn ratio?
  • Ans. 

    Turn ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer.

    • Turn ratio determines the voltage transformation ratio in a transformer.

    • It is calculated by dividing the number of turns in the primary winding by the number of turns in the secondary winding.

    • For example, if a transformer has 100 turns in the primary winding and 200 turns in the seconda

  • Answered by AI
  • Q6. What is the emf equation of transformer?
  • Ans. 

    The emf equation of a transformer relates the induced voltage to the number of turns in the primary and secondary coils.

    • The emf equation of a transformer is given by: E = N*dΦ/dt, where E is the induced voltage, N is the number of turns, and dΦ/dt is the rate of change of magnetic flux.

    • This equation shows that the induced voltage in a transformer is directly proportional to the number of turns in the coils and the rate...

  • Answered by AI
  • Q7. 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).

    • Examples: A light bulb draws current from a power source to produce light. A fan motor requires current to spin.

  • Answered by AI
  • Q8. What is potential transformer
  • Ans. 

    A potential transformer is a type of instrument transformer used to step down high voltage to a lower, safer voltage for measurement or control purposes.

    • Used to step down high voltage to a lower voltage for measurement or control purposes

    • Provides accurate voltage measurements for meters and relays

    • Commonly used in power systems for protection and metering applications

  • Answered by AI
  • Q9. What is inductance
  • Ans. 

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

    • Inductance is measured in Henrys (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 circuits to store energy in the form of a magnetic field

  • Answered by AI
  • Q10. What is capacitance
  • Ans. 

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

    • Capacitance is measured in farads (F).

    • It is the ability of a capacitor to store energy in an electric field.

    • Capacitance depends on the geometry of the capacitor and the dielectric material between the plates.

    • Capacitance is calculated as C = Q/V, where C is capacitance, Q is charge, and V is voltage.

  • Answered by AI
  • Q11. What is unit of inductor
  • Ans. 

    The unit of inductor is Henry (H)

    • The unit of inductor is named after American scientist Joseph Henry

    • It is represented by the symbol 'H'

    • 1 Henry is equal to 1 volt-second per ampere
