(4 Questions)

  • Q1. What is power system?
  • Ans. 

    A power system is a network of electrical components used to generate, transmit, and distribute electrical power.

    • Power systems consist of power plants, transformers, transmission lines, and distribution networks.

    • They are designed to deliver electricity from power plants to consumers.

    • Power systems can be categorized into three main types: generation, transmission, and distribution.

    • Examples of power systems include the e...

  • Q2. What is the formula of I sequre R?
  • Ans. 

    The formula for I squared R is used to calculate the power dissipated in a resistor.

    • I squared R is equal to the current (I) squared multiplied by the resistance (R)

    • It is commonly used in electrical engineering to determine the power loss in a resistor

    • For example, if the current flowing through a resistor is 2A and the resistance is 5 ohms, the power dissipated can be calculated as (2^2) * 5 = 20 watts

  • Answered by AI
  • Q3. What is rectifier ,and its work ?
  • Ans. 

    A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

    • Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

    • They consist of diodes that allow current to flow in only one direction.

    • Rectifiers are used in various applications such as battery charging, electroplating, and welding.

    • Examples of rectifiers include half-wave rectifiers, full-wave rectifie

  • Answered by AI
  • Q4. 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, called the primary and secondary, wrapped around a magnetic core.

    • When an AC current flows through the primary coil, it creates a magnetic field that ind...
