why don’t power lines and towers short-circuit during rain

There’s no doubt that electricity is the most basic necessity of the modern world. Without electricity, there is hardly anything which will work in today’s world. Right from the day electricity was first discovered by Benjamin Franklin, its use and development have always seen a northern trend as the demand is ever increasing and distribution through the power line, thanks to the ever growing technology.

Electricity can be considered as the heart of any technology that we come across on his planet.

Have you ever wondered what electricity basically is?

Power line

In simple terms, it can be regarded as a flow of ions from a positive to negative charge. For this charge to flow you generally require a medium which is known as a ‘conductor’. A conductor in simple terms is anything which allows electricity to flow through it freely, i.e, without any resistance.

The more the resistance, fewer will be the amount of electricity flowing through any material. An insulator, on other hands, doesn’t allow electricity to flow through it. Wood, for example, is known to be a good insulator. There’s hardly any material which can be regarded as a perfect insulator. This is because even if a material is a good insulator if you flow a very high current through it, it will give you a shock.

That is because each and every insulator in power line has a capacity to provide resistance to the current flowing through it and when that barrier breaks the current is able to flow through the material and in turn through anyone touching that material.
