Learn more WhatsAppPositive and negative terminals: The battery circuit diagram typically includes symbols to represent the positive and negative terminals of a battery. The positive terminal is represented by a longer line or a plus sign (+), while the negative terminal is represented by a shorter line or a minus sign (-).
Learn more WhatsAppThe above image shows a Mylar film capacitor. The top "683" marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF). There are …
Learn more WhatsAppPolarized capacitors are only rated for voltage potentials in one direction. They like to collect charge in one polarity on their plates. A non-polarized capacitor such as generic ceramic types are capable of collecting charge in both positive and negative polarity (you can use them in circuits that have voltages that swing both above and …
Learn more WhatsAppPolar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor. These type of capacitors are only used in DC applications.
