Wavelength, period and frequency are closely related to each other. By definition, wavelength is just the distance between two identical points in the adjacent cycles of a wave, and […]
Current, voltage and resistance are basically the three things we need when analyzing a circuit. An electrical circuit is basically a path that can conduct electricity, in other words, it […]
In electrical science, Ohm’s Law is so useful that it helps engineers to calculate either current, voltage, or resistance, if any two of these factors are given. Actually Ohm’s […]
