What is current?

Quick answer:

Flow of electrons

The electrons are charges; we are getting energy of electrons. So electrons total flows are occur in electricity.

What is voltage?

Quick answer:

Potential difference between the two ends of conductors.

We need electrons charges for electricity. But flow of electrons force is not enough with making potential difference. If we have no potential difference we don’t getting electrons flows continuously.

What is power?

Power = voltage × current

We are getting current through potential difference so that totally called power. We are talking usually, current or voltage or charge. These words are misconception. Power is a correct word for electrical energy.

Why need good conductor for electricity?

Because of free electrons are used to conductivity. Conductors have free electrons and that free electrons are used to conduct external electric motive force to the devices. If we use good conductor, the conductivity is high because of more free electrons.

First we should understand these points, and then come to the topic.

Why does birds are not getting an electric shock when it sits on the electrical wire?

A bird sitting on live wire will get a shock only if the electric current passes through its body. We can compare the flow of electricity through a body to the flow of water.  Like in water flow, electric current always flows from a higher potential level to a lower potential level.

The two wires in an electric post are kept in different potentials. One wire, which we call live, will be at a high potential, and it is the phase wire.

The other wire is neutral and its potential is zero. On sitting on the live wire, the bird’s potential will also be raised to the same potential as the wires.

We saw birds are sitting on the electrical line with casual but sometimes it’s getting shock. Do you think why it’s happen rarely?

If it comes in contact with the neutral wire, a current will pass through its body from the live wire to the neutral wire. Then the bird gets an electric shock. The bird can sit on the live wire without getting electric shock as long as it does not tough the neutral wire.
