seriemotstånd

Seriemotstånd refers to the electrical phenomenon where multiple resistors are connected in a series configuration. In such an arrangement, the current has only one path to flow through each component sequentially. The total resistance of a series circuit is the sum of the individual resistances of each resistor. This means that if you have resistors R1, R2, and R3 connected in series, the equivalent resistance (R_total) is calculated as R_total = R1 + R2 + R3.

A key characteristic of seriemotstånd is that the current flowing through each resistor in the series is the same. However, the voltage across each resistor will differ depending on its resistance value, according to Ohm's Law (V = I * R). The total voltage supplied to the series circuit is divided among the resistors. If one resistor in a series circuit fails or is removed, the entire circuit is broken, and current will stop flowing. This is in contrast to parallel circuits, where each component has its own separate path for current. Seriemotstånd is a fundamental concept in basic circuit analysis and is used in various applications, such as voltage dividers and current limiting.
