Basic Electronics How to test electronic components Test capacitors Low-value capacitors The proof of low-value capacitors is limited to whether or not these are shorted. 100nF Values below are generally not detected by the multimeter and the same position R × 1k test can tell if the capacitor is shorted or not as shown.

If the capacitor has infinite resistance means that the component does not have excessive losses or is shorted. Usually this is enough indication to believe that the capacitor is in good condition but in some cases it may be that the item was "open", or a terminal inside the capacitor does not make contact with the plate. To confirm with certainty the state of the capacitor and even know their value, you can use the circuit in Fig.

To know the value of capacity should follow the steps outlined below:

1. Armed circuit voltage V1 is measured and recorded. 2. Calculate the current through the resistor that is the same as going through the capacitor to be two elements in series I = V1 / N 3. Voltage V2 is measured and recorded. 4. Calculate the capacitive reactance component in measuring XC = V2 / I http://www.scribd.com/k arlozmxmty

5. Calculate the value of the capacity of the capacitor with the values obtained C = 1 / [XC. 6, 28. f] Observations You must use a single voltmeter. The frequency is 50 or 60Hz depending on the country where you are because it is relevant to the electricity grid. Choose the R-value as the capacitor value to be measured: Ability to measure - Endurance series 0, 01uf
