The study of how electricity is used is known as electronics. This includes a wide range of uses, including operating computers, cars, home appliances, and robots. Of course, it is impossible to learn everything there is to know about all of these gadgets in a single, brief course, but the knowledge you gain from this one will give you a solid foundation from which to observe and comprehend how everything in your environment that is powered by electricity functions.
This course by itself enables you to make wiser choices regarding the electric appliances you employ, as well as how to maintain and fix them. More specifically, this course can serve as a springboard for formal or informal learning that comes later.
You will get understanding about electric circuits and how to comprehend them in a variety of situations, which can be used to support using computers.
By applying electrical pressure from an electricity source, electricity passes through a conductor. The power source could be a generator, a power point, a battery, or an alternator powered by an engine (indirectly a source from a power station).
Electricity can only flow from the source, via the conductors, and back to the source if there is an uninterrupted circuit of conductors. The flow of electricity will stop at any point when the circuit is broken (like a switch). A certain degree of flow resistance exists in every circuit. The flow will be reduced as the resistance is increased.
Materials that transfer electricity are known as conductors. Different conductors transmit electricity differently. Among the best conductors, including metals, carbon, and water, are copper and silver (if it contains some impurity: pure water is not a good conductor).
CONDUCTORS OR INSULATORS
Insulators, such as plastic, rubber, wood, and glass, can be used to insulate against electricity since they do not carry energy.
Fuses are used to safeguard the operator and the circuit.
By using too many appliances, numerous adapters, or broken equipment, electrical circuits can get overloaded. This may result in an excessive current flow, which could lead to overheating or possibly a fire. Fuse placement in the circuit limits the amount of current that can flow in order to avoid this happening. The fuse wire melts when the current rate for a particular fuse is exceeded as a result of overloading. This disrupts the circuit and halts the flow of electricity.
