jänniteerottelu
Jänniteerottelu, often translated as voltage division, is a fundamental concept in electrical engineering describing how voltage is distributed across components in a series circuit. When resistors are connected in series, the total voltage applied across the combination is divided among them in proportion to their resistances. This means that a larger resistance will drop a proportionally larger share of the total voltage.
The principle can be understood using Ohm's Law, which states that voltage (V) equals current (I) multiplied
Voltage dividers are widely used in electronics to create a lower voltage from a higher voltage source.
