The bridge rectifier

Simple explanation of ac to dc. The ac at input changes its polarity 50 times a second (60 in the USA). The above image is deliberately made slow at the rate of 1 per second to understand the same. Watch the output  DC in red that remains always +ve. and black -ve. This dc, however, is not pure DC it is called pulsating DC though it can be used for some applications. To get pure DC a lot of filtering is needed. The Smoothing Capacitor We know that the single stage half-wave rectifier creates a yield wave each half cycle and that it was not viable to utilize this sort of circuit to deliver a relentless DC supply. The full-wave span rectifier, on the other hand, gives us a more prominent mean DC esteem (0.637 Vmax) with less superimposed pulsating…

Components

Let us understand first 2 electronics components  mostly used in circuits Resistor (can call it resistance) Capacitor While you come across a circuit the above 2 components are mostly seen.The basic function of resistor is to oppose current flow while for a capacitor its function depends upon whether it is working in an ac circuit or a DC circuit. In ac applications it is somewhat similar to resistor but in DC application it is like a storage tank. It stores some energy.
