I WONDER - What Is A Battery?

A battery is a device that stores energy and can power other devices by converting chemical energy into electrical energy. It consists of one or more cells, each with two electrodes: a positive electrode called the anode and a negative electrode called the cathode, separated by an electrolyte.

What is the primary function of a battery?

• To create sound

• To store and convert energy

• To generate heat

• To produce light

How does a battery convert energy?

• From thermal to mechanical

• From chemical to electrical

• From electrical to chemical

• From mechanical to thermal

What are the main components of a battery cell?

• Anode, cathode, and electrolyte

• Anode, diode, and transistor

• Cathode, resistor, and capacitor

• Electrolyte, wire, and switch

Which part of the battery is known as the positive electrode?

• Resistor
