Question: what are the principles of double entry accounting

title: Double-entry bookkeeping system
text: Debits are recorded on the left side of a T account in a ledger . Debits increase balances in asset accounts and expense accounts and decrease balances in liability accounts , revenue accounts , and capital accounts . Credits are recorded on the right side of a T account in a ledger . Credits increase balances in liability accounts , revenue accounts , and capital accounts , and decrease balances in asset accounts and expense accounts . Debit accounts are asset and expense accounts that usually have debit balances , i.e. the total debits usually exceed the total credits in each debit account . Credit accounts are revenue ( income , gains ) accounts and liability accounts that usually have credit balances .
