Explanation:

Resonance is the delocalisation of #pi# electrons in a conjugated system.The different structures formed by resonance are called resonating structure or canonical forms and the equivalent structure formed represents the actual structure of a molecule.

Resonance occurs in a conjugated system only and it occurs to stabilize the system as:

#"Number of resonating structures " prop " Stability of compound"#
A conjugated system is formed by alternate #pi# - #pi# or #pi# electrons with negative charge or #pi# electrons with positive charge, etc.
