Most of the electricity is generated by fossil fuels such as natural gas, coal, and nuclear energy. However, many countries around the world are using alternative sources such as hydropower, biomass, geothermal, and solar power. In science, the First Law of Thermodynamics states that energy can...
The basic premise is electricity powers motors instead of gasoline combusting inside engines. This makes EVs faster, quieter, cleaner, and cheaper to operate per mile. Supporting components like cooling systems, DC/DC converters, charge ports, transmissions, and electronics also play key roles in ...
Studying the origin and definition of electricity or electric current is essential to understanding its various applications. Electric current in conductors is defined with respect to free electrons that exhibit random zig-zag motion within the conductor. It is the flow of charged particles, ...
Health services are a basic necessity for a person. Private companies have made health services quite costly for ordinary individuals. Do the advantages of private health care outweigh its disadvantages? Give reasons for your answer and include any relevant examples from your own knowledge or experien...
A capacitor is a passive electrical component that can store energy in the electric field between a pair of conductors (called “plates”).In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also ...
One possible classification is by intended use, e.g., research, plutonium production, electricity generation, or propulsion units for submarines or surface ships. In this chapter we will concentrate on power reactors, both on account of their practical importance and because of the complexity in ...
Artwork: The basic concept of a piezoelectric accelerometer: as the gray accelerometer box moves right, the mass squeezes the blue piezoelectric crystal (very exaggerated in this picture), which generates a voltage. The bigger the acceleration, the bigger the force, and the greater the current ...
These types of diodes can also be used to generate electricity. For some applications, PIN diodes work very well as photodetectors. Read more about . . . . Photo diode. PIN diode: This diode type has areas of P-type and N-type silicon, but between them there is an area of intrinsic...
A single integrated circuit (IC), such as a microprocessor chip, can do the work of a set of vacuum tubes.Semiconductor MaterialsThere are several materials and elements used to make semiconductor. The basic requirement is that the material should not be a very good conductor of electricity, ...
Circuit breakers accomplish their function through mechanisms known as thermal or magnetic breakers, which block the current of electricity between live wires and the circuit's conductor. When the conductor makes contact with the wires, the flow of electricity is allowed to resume....
