Unlike resistance which is not dependent on frequency, in an AC circuit reactance is affected by supply frequency and behaves in a similar manner to resistance, both being measured in Ohms. For example, the capacitor is either being charged or discharged on a continuous basis at a rate determined by the supply frequency. Likewise, when the supply voltage is reduced the charge stored in the capacitor also reduces and the capacitor discharges. This then results in a frequency-dependent RC voltage divider circuit. We can see from the above examples that a capacitor when connected to a variable frequency supply, acts a bit like a frequency controlled variable resistor as its reactance (X) is inversely proportional to frequency. This is because every circuit has resistance, capacitance, and inductance even if they don't contain resistors, capacitors, or inductors.. For example, even a simple conducting wire has some amount of resistance, capacitance, and inductance that all depend on the material composition, gauge (i.e. As the frequency increases, the capacitor passes more charge across the plates in a given time resulting in a greater current flow through the capacitor appearing as if the internal impedance of the capacitor has decreased. One plate of a capacitor having a charge of +q coulombs, and the other plate has an equal but opposite charge of -q coulombs. In the RC Network tutorial we saw that when a DC voltage is applied to a capacitor, the capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage. The relationship between the voltage across the inductor is linearly related by a factor L, the inductance, to the time rate of change of the current through the inductor. 19, we obtain an formula of the form Q = I dt + c where c is the initial charge, if available.
