When capacitive and inductive reactance are equal, what is the result on the circuit?

When capacitive and inductive reactance are equal, the result on the circuit is that they cancel each other out. This situation occurs in a condition known as resonance, where the capacitive reactance (which opposes changes in voltage) and inductive reactance (which opposes changes in current) are balanced.

In this balance, the net reactance of the circuit becomes zero, leading to a purely resistive circuit at the resonant frequency. This means that the circuit can conduct maximum current without increasing voltage significantly due to the equal but opposite effects of the capacitive and inductive components.

As a result, at resonance, the total impedance of the circuit is minimized, allowing for efficient energy transfer and the potential for increased current flow, assuming the circuit has some resistive components. This characteristic is essential in various applications, including tuning circuits and filters, where maintaining a precise balance between inductive and capacitive reactances is crucial for desired performance.
