Checking 2.2uf Electrolytic Capacitors with Ohmmeter, Voltage Changes, and Lifespan

Hello.
I have some questions about damaged electrolytic capacitors:
1. Can capacitors with a capacity greater than 100, e.g. 2.2uf, be checked with an ohmmeter?
2. Will it show other voltage after charging the capacitor with eg 5V voltage?
3. How old do electrolytic capacitors withstand?

1. Since when the capacitors are checked with an ohmmeter? For this purpose, capacitance meters and ESR are used.
2. If you connect a voltage source to the capacitor, then after charging it should be the same voltage.
3. It depends on the quality of workmanship and conditions in which the capacitors are working (temperature, operating frequency, etc.)

I will try harder than for a student, it does not mean better
ad1. With an ohmmeter you will check only if the capacitor has a typical short circuit on the covers, if it has a short circuit it is known to be damaged, but if it does not have it it can still be damaged, i.e. the measurement is very little worth. The ohmmeter also charges the capacitor so it can be charged from the ohmmeter. It can have a large leakage, so after charging it will quickly lose voltage on the electrodes, it may have a lower capacity - because the electrolytes dry out, etc.
Generally, the colleague above wrote what the capacitor is measuring. Before every measurement and connection to the meter, the capacitor should be discharged.

ad.2 As above, but if it was a small capacity capacitor, you will notice that the voltage will slowly drop because the meter itself will be discharged, and how fast it depends on what meter, digital very slowly and unnoticed, old analog one minute faster, everything depends from the resistance of the meter and the capacity of the capacitor. It may be very difficult to notice this drop in a reasonable time.
ad.3 I will not add anything Oh, you can say that from the manufacturer, because:

I have a meter for PLN 20 from the uni-t company

If it is not possible to measure the capacity (many modern cheap meters already have this option) you can check if it has a puncture or not. Besides, by measuring alternately (changing the probe tip before each measurement) you can LESS find out (you need some practice and comparisons with a capacitor with the same capacity) or load quickly or slowly and in this way (in a huge approximation) estimate its capacity.
Col. Jawi_P wrote about it above.

And how to check capacitors with small and very small capacitances, e.g. 4,7uf, 0,1uf.

You need a meter that can measure the capacity of capacitors and their ESR otherwise you will not check.

I know. I close the topic.
