Used on it's own, a digital multimeter set for resistance, will not give you a value. You can however determine if the capacitor has totally failed.
If you measure the resistance of an electrolytic capacitor, you should get a rising reading, going from near zero and rising up to maximum resistance. If you then immediately reverse the leads, you should get a negative reading, dropping through zero and then rising again to maximum resistance.
The speed at which this happens is a function of the capacitance. A high value will take longer to change value.
Some capacitors may fail short circuit and this will be immediately evident with a zero resistance reading. Some may fail open circuit, where you will not detect a change in value when reversing the leads, but will instead get an infinity reading.
This only works with high value capaitors, above 5uFd, electrolytic or tantalum bead.

How test resistances?
we can measure the resistance if we know the voltage and current passing through a line (V=IR)AnswerYou can measure its approximate resistance using an ohmmeter, but ohmmeters aren't particularly accurate. A better way would be to use a Wheatstone Bridge, which is highly accurate.
How capacitors are tested?
first you need a analog multimeter. put in your meter in the ohm section x10. then remove the cap in the ckt and discharge that. then connect the multimeter -ve probe to the cap +ve terminal and connect the other terminals.the needle comes to low value then com to infinity, remove the probs then connect multimeters -ve prob to the cap -ve terminal that time look carefully the meter's needle comes to the one value and go back to the infinity that the low value is capacitors equivalent resistance value. the cap is 1000uf the equivalent resistance value is around 15 at x10 .the cap is 100uf the equivalent resistance value is around 15 at x100
What is the difference between an Insulation Resistance Test and a Continuity Test for Electric Cables?
A continuity test checks to ensure that there is no break in the conductors. An insulation test checks to ensure that the insulation is sound.
How do you test for a digital signal?
using LED.when the signal is 1,then the LED glows,but when signal is 0,then it does not glow.

When was The Electric Kool-Aid Acid Test created?
The Electric Kool-Aid Acid Test was created in 1968.
How do you use tempo PE961 to test digital sets?
Other than listening for data noise when set to "Monitor", there's no way to test a digital extension with an analog device. The 'test set' would have to made specifically for the digital system being used.
How to test for electric short?
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
Why we use the positive test charge for determining the electric field?
A positive test charge is used to determine the electric field because its direction of motion will be the same as the direction of the electric field. This allows us to measure the electric force experienced by the test charge and therefore calculate the electric field strength at that point.
Why multimeter cannot used for measurement of insulation resistance?
Because ordinary ohmmeters are calibrated to measure a range of resistance values that are significantly lower than the resistance of insulation. It should also be realised that we usually test insulation resistance while subjecting the insulation to a high electric field, which a normal ohmmeter is incapable of producing.

How can one determine the strength of an electric field?
The strength of an electric field can be determined by measuring the force experienced by a test charge placed in the field. The greater the force experienced by the test charge, the stronger the electric field. The formula to calculate the electric field strength is E F/q, where E is the electric field strength, F is the force experienced by the test charge, and q is the magnitude of the test charge.
When determining an electric field must a positive test charge be used or would a negative one do as well?
Either a positive or a negative test charge can be used to determine an electric field. The direction of the electric field will be defined by the force experienced by the test charge, with the positive test charge moving in the direction of the field and the negative test charge moving opposite to the field.
