What is Current, Voltage, Resistance - Explain in Bangla

Current,Voltage,Resistance

Define current, voltage, and resistance units together?

Current :

Current is the rate at which the free electron mass flows in a certain direction between the conductors of matter.

It is expressed as I or i. The unit of current is the coulomb/second or ampere. Its symbol is A, its unit is Amp.

Voltage:

The force required to displace conductive atoms is called the electric conductor force or emf or voltage. Its symbol is V, the unit being Volt.

Resistance:

When a current flows through a conductor, the characteristic or nature of the material of the conductor that interferes with it is called resistance. Its symbol is R or r.  It is expressed by the ohm sign.
