How many ohms should a capacitor have? A capacitor should not have any ohms. This is because capacitors are designed to not have any electrical resistance, so if it reads 0 ohms then something has gone wrong with the component. If a capacitor reads anything other than 0 ohms, it means that the device has failed and should be …
How Long Does It Take for a Microwave Capacitor to Discharge?
4) Capacitor Age and Condition. Over time, capacitors may deteriorate or degrade, which can affect their ability to hold a charge. Aging capacitors may exhibit higher leakage currents, leading to faster discharge rates. Therefore, the age and condition of the capacitor can influence how long it retains a charge .

for. Trimmer capacitors are still the best way to achieve optimum circuit performance at the least overall cost. For instance, after burn-in and temperature cycling, crystals can drift but can be brought back to the exact frequency with trimmer capacitors. Trimmers have taken their share of knocks over the years on several counts.
