Concept
Ohm's Law is a fundamental principle in electronics and electrical engineering that states the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. This relationship is mathematically expressed as V = IR, where V is voltage, I is current, and R is resistance.
Concept
In a series circuit, components are connected end-to-end, so the same current flows through each component. This configuration means that the total resistance is the sum of individual resistances, and a break in the circuit stops the flow of current entirely.
