Electrical Energy

The voltage of a big lightning cloud could additionally be as excessive as 100 MV and have discharge energies as great as 250 kWh. How, precisely, the tiny magnetic fields are generated depends on how electrons move inside atoms. This is one example of how magnetism and electrical energy are related. Alternating present is certainly one of the types of electrical current. In this sort of current, the direction of charge conduction adjustments quickly, causing electrons to circulate in reverse directions periodically.

Lesson What Is Electricity?

In this determine, the alternating present completes one cycle every second, i.e. it has a frequency of 1 Hz. Note that a negative present represents a present in the different way. In direct current , electrons all move in the identical direction.
