Question

Does the resonating structure have same amount of energy content or not

Answer 1

Yes

Answer 2

Resonating structures (canonical forms) are hypothetical representations of a molecule that collectively describe its electronic structure. By definition, these individual canonical forms are considered to have the same energy content and the same arrangement of nuclei. The actual molecule, which is a resonance hybrid, has an energy lower than any of these individual canonical forms, resulting in increased stability due to electron delocalization.
