Explanation:

A debit balance is an account balance where there is a positive balance in the left side of the account. Accounts that normally have a debit balance include assets, expenses, and losses.
A debit balance is a negative cash balance in a checking account with a bank. Such an account is said to be overdrawn, and so is not actually allowed to have a negative balance - the bank simply refuses to honor any checks presented against the account that would cause it to have a debit balance. Alternatively, the bank will increase the account balance to zero via an overdraft arrangement.
