What is the difference between resistance and reactance?
What will be an ideal response?
Resistance is a physical property of every electrical conductor, which restricts or opposes the flow of electrical current. It can be read with an ohmmeter and when current flows through resistance, heat is dissipated and there is a power loss.
Reactance is an opposition to current flow in an electrical circuit that prevents the current’s flow in the first place. It cannot be measured with an ohmmeter and needs to be calculated. There are no power losses or head loss because it prevents current from happening.
