相同參數的兩個電容并聯后，電容的耐壓值不變，但是容量翻兩倍！

相同參數的兩個電容串聯后，耐壓值增加了兩倍，但是容量會減半！

相同參數的兩個有極性電容背靠背反向串聯后就組成了無極性電容，電容的耐壓值不變，容量值減半！

 Three States of Capacitors After Parallel or Series Connection

When two capacitors with the same parameters are connected in parallel, the voltage rating remains unchanged, but the capacitance doubles!

When two capacitors with the same parameters are connected in series, the voltage rating triples, while the capacitance is halved!

When two polar capacitors with the same parameters are connected in reverse series back-to-back, they form a non-polar capacitor. The withstand voltage value of the capacitor remains unchanged, and the capacity value is halved!
