What is the fine for giving fake identity to a ticket inspector in London?

I was going to get fined. I tried to explain to the ticket inspector why I didnt touch in my oyster card. The ticket inspector asked me my name and address. I lied to him about my identity. He verified but he said he was going to call the police. So I told him my real identity. He said I am going to court. So round how much will I get fined by the court and which court will I be asked to go to?
