How to Convert AC to DC

This article talks about how to convert Alternating Current (AC) to Direct Current (DC). As almost all Electronic devices and circuits use Direct Current (DC) instead of Alternating Current (AC) directly, there is a need for a DC. Though, for a novice it may seem as if is an AC powering Electronic because is plugged …

Capacitors in series calculation

Capacitors in Series calculations

In this post we will be looking at Capacitors in series calculations. Capacitors in series are connected end to end so that the same charge (Q) appears across each of them. Meanwhile, in this connection, different potential difference (Pd) appears across each of the capacitors. The sum of voltage drops across each of the capacitor …
