PNP transistor is a semiconductor device with a structure opposite to that of an NPN transistor. It has an N-type layer situated between two P-type layers. In a PNP transistor: When you apply current to the base of a PNP transistor, which controls the current between the emitter and the collector, the transistor turns on. …
NPN transistor is a semiconductor device used as a switch or amplifier of electrical signals. It has a structure opposite to that of a PNP transistor. In an NPN transistor: It consists of three semiconductor layers – one N-type (negatively charged) layer located between two P-type (positively charged) layers. To open and activate an N-P-N …
The Law of Conservation of Electric Charge states that electric charge cannot be created or destroyed; it can only be transferred from one body to another.
Speed of light The speed of light is the highest speed achievable in a vacuum of space, and it is equal to 299,792,458 meters per second. This speed was discovered and experimentally measured in the second half of the 19th century, and according to Albert Einstein’s theory of relativity, it is a fundamental constant of …
Renewable energy sources are sources of energy that can be continuously used and do not get depleted through utilization.
Current density is a vector physical quantity equal to the ratio of the electric current passing through an elementary surface located perpendicular to the direction of charge movement to its area.
Faraday’s Law is a fundamental law of electromagnetism that describes the interaction between electricity and magnetism. The law was discovered by Michael Faraday in 1831.
