What is the difference between resistance and reactance?

Resistance dissipates energy as heat and is frequency-independent; reactance (of L or C) stores and returns energy and depends on frequency.

Resistance dissipates energy as heat and is frequency-independent; reactance (of L or C) stores and returns energy and depends on frequency. A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
