sarjaliitokset

Sarjaliitokset, known in English as series connections, refer to a method of connecting electrical components or devices in a chain, where the current flows through each component sequentially. This means that the output of one component is directly connected to the input of the next. In a basic series circuit, there is only one path for the current to travel.

The key characteristic of a sarjaliitos is that the total resistance of the circuit is the sum of the individual resistances of each component. Similarly, the total voltage across the series circuit is the sum of the voltage drops across each component. However, the current remains the same through all components in a series connection. If one component in the series fails or is removed, the entire circuit is broken, and current will no longer flow.

Sarjaliitokset are commonly used in applications where a specific total resistance or voltage division is required. For example, connecting multiple resistors in series allows for the creation of a larger, cumulative resistance. Similarly, light bulbs can be connected in series; if one burns out, all the lights go out. This property makes series connections useful for certain safety features, like fuses, which are always placed in series with the circuit they protect. Understanding sarjaliitokset is fundamental to basic electrical circuit analysis.
