Explanation

The fluid in your lead-acid battery is called Electrolyte.

It's actually a mixture of sulphuric acid and water.

Explanation

Battery is a device that converts chemical energy into electrical energy.

Batteries work by using a galvanic cell.

It is an electrochemical device made up of two electrodes and an electrolyte solution.

Explanation

A battery is connected in an electric circuit to provide a constant potential difference (voltage) across the circuit, allowing electric current to flow through the conductors.

The battery maintains a constant voltage, ensuring a consistent flow of current through the circuit.

Explanation

Alessandro Giuseppe Antonio Anastasio Volta was an Italian physicist, chemist.

who is credited as the inventor of the electrical battery and the discoverer of methane.

Explanation

• The batteries in the toy car store chemical energy.
• It is converted into electrical energy when the batteries are connected to the toy car's motor.

Explanation

The battery on a motherboard, often called a CMOS battery

CMOS battery:

Function: It powers the CMOS chip which stores critical system settings. 

What it stores: Date, time, boot sequence, hardware configurations, and sometimes passwords. 

What happens if it fails: If the battery dies, you will likely need to reset the BIOS settings when you turn on your computer, including setting the date and time again.
