.Reactance is the opposition to the flow of alternating current (AC) caused by capacitance or inductance. It is measured in ohms and is represented by the symbol X.
Reactance is directly proportional to frequency. This means that as frequency increases, reactance also increases. Conversely, as frequency decreases, reactance decreases.
When reactance is zero, it means that there is no opposition to the flow of current. This occurs at a specific frequency known as the resonant frequency, where the capacitive and inductive reactance cancel each other out.
Zero reactance is used in practical applications to achieve maximum efficiency in electronic circuits. For example, in a filter circuit, zero reactance can be used to block unwanted frequencies and only allow the desired frequency to pass through.
No, reactance cannot be negative. It is always a positive value, representing the opposition to current flow. However, it can be represented as a negative value in calculations when it is acting in opposition to another form of reactance.
