A) Electric cell and its uses
Answers
Answer:
An electrical cell is an "electrical power supply". It converts stored chemical energy into electrical potential energy, allowing positive charges to flow from the positive terminal to the negative one through an external circuit. This is called a current.
To complete the circuit, the charge must flow from the negative terminal back to the positive one inside the cell. Electrical forces of repulsion oppose this, but the chemical reaction provides larger forces on the charges enabling them to reach the positive terminal ready for another journey around the electric circuit. The voltage across the cell depends on the chemical reaction - a typical value being 1.5 V. To obtain larger voltages, we put the cells in series to make a battery. There are six tiny cells inside each rectangular 9, V,9 V battery.

Answer:
Explanation:
an electric cell is used to power-up simple macheses like remote controls, toys and etc. an electric cell has two types:
rechargable cells like in our phones
non-rechargable cells, which are use and throw cells
there are 2 types of terminals:
positive and negetive
the electricity flows from positive side
move to the device like bulb
and from bulb, it comes back through a wire and ends in negetive terminal
cells are made up of chemicals
