The unit of resistance is the ohm (symbol: Ω). Resistance is a measure of how much a material or device opposes the flow of electric current. It quantifies the degree to which a conductor resists the passage of electrons. The ...

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 ...
Electric current does not flow between two charged objects connected to each other if they are at the same potential. In electrical terms, potential refers to the electric potential difference between two points, determining the direction and amount of current ...
The unit of electric current is the ampere. It is one of the seven base units in the International System of Units (SI) and measures the flow of electric charge through a conductor. One ampere is defined as the flow ...
