62. An electrochemical cell which is used as a source of direct electrical current at constant voltage under standard conditions is called a : A.Power transmittor B.Battery C.Uninterrupted power supply (UPS) D.Generator
Answer: Option B Solution: A Galvanic cell, also known as battery, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. It is typically used as a source of electrical power. By their nature, they produce direct current. A battery is a set of galvanic cells that are connected in parallel.
