Impedance
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied
Reactance
In electrical and electronic systems, reactance is the opposition of a circuit element to a change in current or voltage, due to that element's inductance or capacitance
RLC series circuit
An RLC circuit is an electrical circuit consisting of a resistor , an inductor , and a capacitor , connected in series or in parallel
capacitor
A capacitor is a passive two-terminal electrical component used to temporarily store electrical energy in an electric field
resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element
alternating current
Alternating current , is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current , the flow of electric charge is only in one direction
