Our homes are full of devices-machines-that run on electricity,but we don't use elctricity in our homes only.We need it in schools,hospitals,banks,factories,etc...Electricity brings us health and comfort.For example at home we use it for heating electric fires ,irons and toasters.
We also use electricity to produce shaft power,i.e.,power that we use to run electric motors.For example,washing machines,refrigerators and mixers use this kind of power.Also vehicles such as subway trains,trolley buses and electric locomotives have motors that run on electricity.
There are also some vert special lamps that produce ultraviolet rays and infrared rays.We use both rays in medical treatments.One of the most valuable an dimportant uses of electicity is in producing X-rays.When we look at an X-rayiwe can see the indise of the human body,and in this way physicians,or doctors,can give a more accurate ;that is,correct,diagnosis of an illness.In other words,when a doctor loks at an X-ray he can tell you what kind of an illness you have.
As you can see,when we think about using electricity we can find so many things to be grateful to Benjamin Franklin:)
