Imagine you have a toy car and you want to make it move from one end of the room to the other. To do this, you need to push the car with your hand. Now, your hand is made up of billions of tiny little particles called atoms. These atoms are like little building blocks that make up everything in the world around us.
But not all atoms are the same. Some atoms have more parts than others, and these extra parts can make a big difference in how well they conduct electricity. Conductivity is a measure of how easily electricity can pass through a material, like your hand or the wires in the toy car.
Now, let's say you want to make a wire to connect the toy car to a battery. The wire needs to be made of a material that can conduct electricity well. Metals like copper and silver are very good conductors because their atoms have extra particles called electrons that can move around freely and carry electricity with them.
Other materials, like rubber or plastic, don't conduct electricity very well because their atoms don't have extra electrons that can move around easily. These materials are called insulators.
So, the conductivity factor is a measure of how well a material can conduct electricity compared to other materials. The higher the conductivity factor, the better the material is at conducting electricity. And this is important because we use materials with good conductivity factors to make things like wires, circuits, and electronics that we use every day.
