ögonblicksvärden
Ögonblicksvärden, a Swedish term, translates to "instantaneous values" or "values at an instant." In physics and engineering, it refers to the value of a varying quantity at a specific point in time. This is in contrast to average values or integrated values, which represent a quantity over a duration or a range.
For example, when measuring an alternating current, the instantaneous value describes the current's magnitude and direction
The concept is fundamental in calculus, where instantaneous rates of change are described by derivatives. The
