Frequency formula

1 the state of being frequent; frequent occurrence . 2 the number of times that an event occurs within a given period; rate of recurrence. 3 (Physics) the number of times that a periodic function or vibration repeats itself in a specified time, often 1 second.

Why is frequency so important? When our system’s frequency is at 50 Hz, generators and consumers can safely deliver or withdraw power without impacting the connected equipment . We can get the right frequency range by matching the amount of power that goes into the grid with the amount of power that comes out.

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

At its most basic, frequency is how often something repeats . In the case of electrical current, frequency is the number of times a sine wave repeats, or completes, a positive-to-negative cycle. The more cycles that occur per second, the higher the frequency.
