Question

1. Write a short note on the electric cell .
2. How can you make a simple switch.
​

Answer 1

Answer:

1. An electrical cell is an "electrical power supply". It converts stored chemical energy into electrical potential energy, allowing a flow of positive charges to flow from the positive terminal to the negative one through an external circuit. To obtain larger voltages, we put the cells in series to make a battery.

2. If you are making your own switch, lay the paperclip on the cardboard or wood, push a thumbtack through it, securing it to the board, and push the other thumbtack into the board across from the first so that the paperclip can be rotated to touch both, creating a metal path for electricity to travel.
