【description】：when a polar capacitor is working, the positive potential must be higher than the negative. otherwise, the leakage of the capacitor ---- if it is light, the circuit will not work, if it is heavy, the capacitor will explode.
if the capacitance capacity is very small, the withstand voltage is very high, and the working voltage is low, nothing can be seen from the reverse connection; if the capacity is slightly large (above 100uf), the withstand voltage is close to the working voltage, and the capacitance will not be damaged for more than 10 minutes, the bad form is: first bulge, then blow, and then burst.
the reverse connection of polar
capacitor will explode, not directly connected to the ac power supply. because this polar
capacitor design is used for dc power supply and filtering, polarity capacitance cannot be reversed
when a polar capacitor is working, the positive potential must be higher than the negative. otherwise, the leakage of the capacitor ---- if it is light, the circuit will not work, if it is heavy, the capacitor will explode.
