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
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.
After a point, the capacitor holds the maximum amount of charge as per its capacitance with respect to this voltage. This time span is called the charging time of the capacitor. When the battery is removed from the capacitor, the two plates hold a negative and positive charge for a certain time.
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.
This equation can be used to model the charge as a function of time as the capacitor charges. Capacitance is defined as C = q/V C = q / V, so the voltage across the capacitor is VC = q C V C = q C. Using Ohm’s law, the potential drop across the resistor is VR = IR V R = I R, and the current is defined as I = dq/dt I = d q / d t.
The Average power of the capacitor is given by: Pav = CV2 / 2t where t is the time in seconds.
