vastuksissa

Vastuksissa is Finnish for “in resistors” and functions as the inessive plural form of vastus, meaning resistance. In technical writing, vastuksissa is used to refer to phenomena, properties, or components that exist inside or among resistors within an electrical circuit. The term is not a separate device or concept, but a linguistic way to describe voltages, currents, temperatures or other characteristics associated with resistors.

A resistor is a passive two-terminal component that provides resistance to current flow. It is measured in ohms (Ω). Fixed resistors maintain a constant resistance, while variable resistors (such as potentiometers or rheostats) allow the resistance value to be changed. In circuit design, resistors are commonly connected in series or in parallel. In series, the same current passes through all resistors and the total resistance is the sum of individual resistances. In parallel, the voltage across each resistor is the same, and the total resistance is found from 1/R_total = sum of 1/R_i.

Ohm’s law describes the basic relationship among voltage (V), current (I) and resistance (R): V = IR. Power dissipation in a resistor can be expressed as P = I^2R = V^2/R. Practical considerations include tolerance (how much a resistor’s value may vary from its nominal rating), and temperature coefficient, which describes how resistance changes with temperature.

In Finnish electronics contexts, references to vastuksissa are common when detailing how voltages, currents or heat behave within resistors or when comparing configurations in resistor networks.
