Current ratios and acid-test ratios are types of liquidity ratios.

Current ratios and acid-test ratios are both examples of liquidity ratios, which are used to measure a company's ability to meet its short-term obligations. The current ratio measures a company's current assets relative to its current liabilities, while the acid-test ratio (also known as the quick ratio) measures a company's ability to pay off its short-term debts using only its most liquid assets (such as cash and accounts receivable).
