When connected to a cell or other power supply, electrons will flow from the negative end of the terminal and build up on one plate of the capacitor. The other plate will have a net positive charge as electrons are lost to the battery, resulting in a potential difference equivalent to the voltage of the cell.
What''s the role of the capacitors? The two 470 pF are in series across the line so, ignoring the 47 pF capacitor, the two 470 pF act together as a single capacitor of value of 235 pF. This is commonly used and, it ensures that any RF pickup on the cable that might otherwise feed into the transformer (as a differential signal) is largely ...
Capacitors in AC circuits play a crucial role as they exhibit a unique behavior known as capacitive reactance, which depends on the capacitance and the frequency of the applied AC signal. Capacitors store electrical energy in their electric fields and release it when needed, allowing them to smooth voltage variations and filter …
