Final answer:
A T-account is a visual representation used in accounting to record debits and credits for transactions in an account. The two sides of a T-account represent debits on the left and credits on the right.
Step-by-step explanation:
In accounting, a T-account is a visual aid that represents a ledger account and is used to depict the effects of transactions on an account. The structure of a T-account includes space at the top for the account title and two sides for recording entries. One side is for debits and the other for credits. To answer the student's question, a T-account has space at the top for the account title and two sides for recording debits and credits to the account. These terms are foundational in double-entry bookkeeping, where each transaction affects at least two accounts, with a debit recorded on the left side and a credit on the right side. The increase or decrease in the account balance depends on the type of account in question (assets, liabilities, equity, expenses, and revenue) and the nature of the transaction.
