Question

Define convection and electric current.

Answer 1

Convection and electric Current
-------------------------------
Here are defination
-------------------------------

Convection :- The process through which the heat passed through the air, water or from vacuum it is called as convection.

Electric Current :- The flow of the electricity's in the electronic circuit is called the electric circuit.

Answer 2

Hey!

__________

Current is amount of charge that can flow in a unit time.

1 ampere = 1 coloumb / 1 second

There are two types of current-:

• Convection current - Before the study of structure of atom, it was considered that it was the +ve charges that flow through the conductor from +ve terminal to -ve terminal, the direction of current is called as convectional current, that is in form of +ve and -ve.

• Electronic current - After study of structure of atom, it was known that it is electrons that actually flow through the conductor but not the protons. Direction of flow of electrons is from negative terminal to positive terminal. This direction of current from -ve terminal to +ve terminal is called electronic current.
