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 work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil of wire.
Transformers consist of two coils of wire, called the primary ...
Power is generated at power plants and then transmitted through high voltage transmission lines to substations. From there, it is distributed to homes and businesses through low voltage distribution lines.
Power is generated at power plants using various sources such as coal, natural gas, nuclear energy, hydroelectricity, wind, and solar power
The generated power is then transmitted through high voltage transmission line...
A substation is a facility that transforms high voltage electricity from power plants to lower voltage for distribution to homes and businesses.
It receives high voltage electricity from power plants
Transforms it to lower voltage for distribution
May have transformers, circuit breakers, and other equipment
May be indoor or outdoor
Examples include distribution substations, transmission substations, and collector substation

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...
Types of transformers include step-up, step-down, isolation, autotransformer, and distribution transformers.
Step-up transformers increase voltage levels
Step-down transformers decrease voltage levels
Isolation transformers provide electrical isolation between circuits
Autotransformers have a single winding with taps for different voltage levels
Distribution transformers are used to supply power to residential and commercia
A capacitor is an electronic component that stores and releases electrical energy.
Capacitors are used in electrical circuits to store energy and release it when needed
They are commonly used in power supplies, motor starters, and electronic filters
Capacitors are characterized by their capacitance, voltage rating, and tolerance
Examples of capacitors include electrolytic capacitors, ceramic capacitors, and tantalum capaci
R. Y. B. stands for Red, Yellow, Blue - the three primary colors used in electrical wiring.
R. Y. B. are the standard colors used for phase conductors in electrical wiring systems
Red is typically used for the R phase, Yellow for the Y phase, and Blue for the B phase
These colors help electricians easily identify and differentiate between the different phases
