Semiconductors use materials like silicon, germanium, gallium arsenide, and silicon carbide.
Common materials used in semiconductors are silicon, germanium, gallium arsenide, and silicon carbide.
These materials have unique electrical properties that make them suitable for use in electronic devices.
Silicon is the most widely used semiconductor material due to its abundance and versatility.
Gallium arsenide is often used i...
Semiconductors are materials that have electrical conductivity between that of a conductor and an insulator.
Semiconductors are used in electronic devices like transistors, diodes, and integrated circuits.
Common semiconductor materials include silicon, germanium, and gallium arsenide.
Semiconductors can be doped to change their electrical properties, such as adding impurities to increase conductivity.
Power generation involves converting mechanical energy into electrical energy through various methods such as steam turbines, hydroelectric dams, and wind turbines.
Power generation involves the conversion of mechanical energy into electrical energy.
Common methods of power generation include steam turbines, hydroelectric dams, and wind turbines.
Steam turbines use steam to drive a generator, converting thermal energy int...
Solar panels generate energy from sunlight by converting sunlight into electricity through photovoltaic cells.
Solar panels use photovoltaic cells to convert sunlight into electricity
The photovoltaic cells are made of semiconductor materials like silicon
When sunlight hits the cells, it creates an electric current
This electric current is then converted into usable electricity for powering homes or devices
A battery is a device that stores chemical energy and converts it into electrical energy to power electronic devices.
Batteries come in various sizes and types, such as alkaline, lithium-ion, and lead-acid.
They are commonly used in electronic devices like smartphones, laptops, and cars.
Batteries consist of one or more cells that contain electrolytes and electrodes.
When a battery is connected to a circuit, chemical react...
Distribution of power.
Solar panels are devices that convert sunlight into electricity by using photovoltaic cells.
Solar panels are made up of photovoltaic cells that capture sunlight and convert it into electricity.
They are commonly used to generate renewable energy for residential, commercial, and industrial purposes.
Solar panels are mounted on rooftops or in open fields to maximize exposure to sunlight.
They are environmentally friendly an...
There are mainly three types of solar panels: monocrystalline, polycrystalline, and thin-film.
Monocrystalline solar panels are made from single-crystal silicon and are known for their high efficiency.
Polycrystalline solar panels are made from multiple silicon crystals and are more affordable but slightly less efficient than monocrystalline panels.
Thin-film solar panels are made by depositing a thin layer of photovoltai...

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
