Question

explain how and why current flows in metals

Answer 1

Hey Sona

As u know metals is formed by ionic or metallic bond and these have charge which transfer the charge from one to other molecules. Thats why metals help to flow current

Answer 2

Metal is considered to be a conductor and when current flows through the conductor, it flows as drift of electrons in the metal.

All conductors contain electrical charges but these move only when there is a potential difference between two diverse points of the conductor. This charge flow is measured in Amperes.

As per the Ohm's law,
V = IR

Direct Current is proportional to the Voltage.

Why electrical current flows and How is it created ?
✓✓✓
Electricity flows easily through conductor because the electrons are free to move in it and whenever there is movement of electrons(charge) ,electrical current is created.

Current I = dq/dt.

Electrical Current is the rate of flow of charge.
