- 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
- 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
- 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...
