In the above diagram, the symbol with one curved plate represents a Polarized Capacitor. The curved plate represents the cathode (negative) of the capacitor, and the other plate is anode (positive). Sometimes a plus sign is also added to the positive side. TheSI unitof capacitance isfarad(...
The value of such a capacitor, essentially it’s “spring constant” for the mechanically–minded, is approximated by the formula in Figure 1 when the separation distance between the plates is small relative to their area. It should be noted however, that mechanical spring constants and capacitor...

with common words is that they're used so often and broadly that they rank poorly and are frequently lost in search results. Select more relevant or industry-specific words. For example, an electronic engineer might prefer to search the wordcapacitorrather than its older, simpler term,condenser...
A resistor is a passive electrical component with the primary function to limit the flow of electric current. The international IEC symbol is a rectangular shape with leads at each end as shown in the figure at left. In the USA, the ANSI standard is very common and represents a fixed resis...
