The algebraic sum of the currents meeting at a point in a circuit is zero. According to Kirchhoff’s current law (KCL), which states that the total current entering a junction (or node) in a circuit is equal to the total ...

Alternating current (AC) is converted into direct current (DC) using a rectifier. A rectifier is an electrical device that converts AC, which periodically changes direction, into pulsating DC by allowing current to flow in only one direction. This process involves ...
When the temperature of a conductor material is increased, its electrical resistance increases while its electrical conductivity decreases. This is because the increased thermal energy causes more frequent collisions between the charge carriers and the atoms in the material, impeding ...
Arsenic is not a semiconductor. Germanium, silicon, and selenium are all semiconductors used extensively in electronics for their ability to conduct electricity under certain conditions, while arsenic, although used as a doping agent in semiconductors, is not a semiconductor itself.
The characteristic of a superconductor is zero permittivity. Superconductors exhibit the unique property of having no electrical resistance when cooled below a certain critical temperature, allowing electric current to flow without any energy loss. This phenomenon is utilized in various ...
