**Resistance And Inductive Reactance And Or Capacitance In A Circuit**- capacitors and capacitive reactance consider the capacitor connected directly to an ac voltage source as shown in the resistance of a circuit like this can be made so small that it has a negligible effect pared with the capacitor and so we can assume negligible resistance the value of resistance is independent of frequency but the value of both an inductive circuit and a capacitive circuit is dependent on voltage frequency if a circuit contains only resistive elements the value of current in an ac circuit can be calculated by the relationship i frac v r bined resistance and reactance in p div class b factrow b twofr div class b vlist2col ul li div author ahmad faizan div li ul ul ul div div div li span class news dt jan 10 2015 span nbsp 0183 32 in a capacitive circuit the current leads the applied voltage across the capacitor the reactance of an rlc series circuit is the circuit power factor.

to measure the electrical resistance of the capacitor and inductor the passive ponents capacitors and inductors are the most widely used in electrical and electronic circuits so whenever a sinusoidal voltage is applied to an inductive coil the back emf opposes the rise and fall of the current flowing through the coil and in a purely inductive coil which has zero resistance or losses this impedance which can be a plex number is equal to its inductive reactance to reduce losses in a circuit the power factor should be as close to unity or 100 as possible this is done by adding capacitive reactance to a circuit when the total reactance is inductive if the total reactance is capacitive inductive reactance is added in the circuit
