Practical Electronics/Sources

Current revision (unreviewed)

Sources that provide Voltage or Current to provide electricity for electrical devices to operate

[edit] Voltage Sources

There are two Voltage Sources are generally used in any applications namely AC and DC Voltage Source

DC stands for Direct Current . Voltage source that has constant voltage that does not change with time and can be expressed mathematically

DC Voltage source are found in Batteries,

AC stands for Alternating Current . Voltage source that has current amplitude varies sinusoidally with time and can be expressed mathematically

v = V_p Sin wt: V_p The highest value of the voltage also called Peak Voltage measured in Volt (v); t - time measured in second (s); w - Angular Frequency . w = 2πf = $\frac{2\pi}{t}$

AC Voltage source are generated from AC generators
