By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
The range in which we can find the actual value of capacitance is between 90 nF and 110 nF. Try the capacitor calculator if you want to find the meaning of the capacitor code and the value of its capacitance. You can also evaluate what is the charge stored in the capacitor for a specific voltage.
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
Thus, you see in the equationt that V C is V IN - V IN times the exponential function to the power of time and the RC constant. Basically, the more time that elapses the greater the value of the e function and, thus, the more voltage that builds across the capacitor.
However, when the capacitance is lower than 100 µF, we can usually find a 3-digit capacitor code that defines the value. The rule is simple: The first and second digits tell us about the capacity in pF (picofarads), while the third one is a multiplier factor (the power of 10) - for the number n, the capacitance is multiplied by 10ⁿ.
These calculations are included in the free Espresso Engineering Workbook. Total capacitance of series-connected capacitors is equal to the reciprocal of the sum of the reciprocals of the individual capacitances. Keep units constant.
