Learn MoreConsider a switch that goes to +5V and a capacitor. When you close the switch, the capacitor will appear as a short and draw high current. As the capacitor charges, and approaches the supply voltage, it draws less current. You saw this this. Now open the above switch, and consider a switch placed across the charged cap.
Learn MoreRun capacitors are prone to various problems over time, and the most common issues include bulging or swelling of the capacitor, leaks on the capacitor''s body, and weak capacitors.

Learn More"Super" capacitor confusion. I do model trains (see relevant user name) and have a number of applications where we pick up power from the tracks (a 12v "ac" source, it''s really DCC, but that probably doesn''t matter here) to power lights, sound, and other items in rolling stock and locomotives. Because the pickup from the track is via wheel-to ...

Learn MoreI''ve re-written this without symbols to try and avoid confusion. I''m having trouble articulating my question. What is the total charge and energy a 100mF capacitor will store if connected to a 12V battery. I''m good with charge. My confusion comes from the 1/2 in the capacity energy formula: 1/2 x [capacitance] x [voltage] 2. If:

Learn MoreConfusion: Definition, Causes, Symptoms & Prevention
Learn MoreThere is confusion about the electric field inside capacitors because it is often mistakenly believed that the electric field is zero inside a capacitor. In reality, the electric field is not zero, but rather varies depending on the distance between the plates and the charge on the plates.
Learn MoreI have some confusion about the negative terminal of a capacitor. Consider the following. Now, my understanding was that postive charges accumulate at the positive ("top") plate of the capacitor, setting up an electric field within the capacitor which causes negative charges to accumulate at the bottom plate.
Learn MoreElectronic devices comprise a wide variety of electronic components. Capacitors, along with resistors and inductors (coils), are regarded as the three major passive components. Today, about one trillion capacitors are produced worldwide each year, 80% of which are multilayer ceramic chip capacitors, and 90% of which are made by Japanese manufacturers.

Learn MoreA capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
