Reactance, also known as impedance, is a measure of opposition to the flow of alternating current (AC) or direct current (DC) in an electrical circuit. It is expressed in ohms and is represented by the symbol 'X'.
Reactance is determined by the resistance of the circuit components, such as resistors, capacitors, and inductors. These components have their own internal resistance, which opposes the flow of current. The higher the resistance, the higher the reactance.
Reactance is an important concept in electrical engineering because it determines the current flow in a circuit and how it affects the voltage and power of the circuit. It also plays a role in calculating the resonant frequency of an AC circuit.
For example, if you have a circuit with a 10 ohm resistor, a 100 ohm capacitor, and a 100mH inductor, the total reactance of the circuit will be equal to the sum of the individual resistances:
This means that the current in the circuit will be limited to 110 A when a 120 V AC voltage is applied.
Overall, reactance is a vital concept in electrical engineering that helps engineers understand and analyze the behavior of electrical circuits
