Polarized Capacitor Schematic Symbol. So there are basically 4 main type of capacitor symbols. Also the negative lead for leaded wet e caps is usually shorter.
The positive or anode side of the capacitor is marked with a symbol. Sometimes a plus sign is also added to the positive side. A polarized capacitor must be connected in circuit accordingly otherwise it will blow up.
The 5 th symbol for capacitor is used in japan.
The have positive and negative terminals and the top of these symbols represent the positive terminals. In the above diagram the symbol with one curved plate represents a polarized capacitor. The american style resistor is drawn as a zigzag resistor while the european style resistor is drawn as a rectangular resistor. Since electrolytic capacitors are polarized i use a symbol shown below on my schematics.
