Narrative:

We were on descent into ZZZ at 11;000 feet; it was -7 sat and ahead; there was a rain cloud so we selected engine anti-ice to on. We flew through the cloud and smelled what the cockpit could describe as 'ozone;' or moisture from the cloud. The a flight attendant called up to the cockpit and said the aft of the cabin smelled a 'faint electrical burning smell.' I told the a [flight attendant] that we flew through a cloud and the smell had gone away and to check if it was electrical and if it was getting worse at all. She came back and called and told me the smell had subsided. It was all within 15-30 seconds.upon landing; I had the a [flight attendant] came up the cockpit and called the aft galley on speaker. I debriefed the crew and we discussed what we smelled; and had decided the smell must have been the passing through the cloud. I left the airplane and a non-revving first officer called me to tell me that he had smelled a 'strong electrical smell.' [he said] that the passengers around him looked alarmed; and one was covering his face. Another non-revving captain told me that he smelled a 'burning oil smell.' I wrote up the incident to have maintenance further investigate what the odor could have been; as there were 3 different smells throughout my aircraft. I had written up and advised maintenance of the discrepancy well after the incident because I didn't know the severity of the odor until the non-revving first officer called me to ask me how I didn't write up a bad fumes event.
