If you see one of these next to a terminal, the capacitor is polarized. Make sure to connect the capacitor's + end to the positive side of the circuit, or the capacitor could eventually cause a short or even explode. [4] If there is no + or -, you can orient the capacitor either way.
Splet25. apr. 2024 · The precaution needs to be taken that the dielectric layer is not damaged or hampered. 2. The second stage is the storage. Capacitors need to be stored in proper temperature. Improper temperature affects the capacitor electrolyte which further downgrades the oxidation layer quality. Splet23. jul. 2024 · Meters measure at a very low voltage.
