Jänniteeroon

Jänniteeroon is a Finnish term that translates to "voltage difference" or "potential difference" in English. It refers to the difference in electric potential between two points in an electric field or circuit. This difference is what drives electric current to flow.

The unit of measurement for voltage difference is the volt (V), named after the Italian physicist Alessandro Volta. A higher voltage difference between two points indicates a stronger electrical pressure, which can cause a greater flow of charge (current) if a conductive path exists between them. Conversely, a lower voltage difference means less electrical pressure.

In a simple circuit, such as one with a battery and a light bulb, the battery provides the voltage difference. The positive terminal of the battery has a higher electric potential than the negative terminal. This difference causes electrons to flow from the negative terminal, through the circuit (including the light bulb), and back to the positive terminal, creating electric current and making the bulb light up.

Voltage difference is a fundamental concept in electricity and is crucial for understanding how electric circuits function. It is a key parameter in Ohm's Law, which relates voltage, current, and resistance in a circuit. Understanding jänniteeroon is essential for anyone working with or studying electrical systems.
