Question

define electric current and state it's unit how can ohm law be used to define ohm​

Answer 1

Answer:

The rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. Unit = ampere

When you are trying to find the resistance in an electrical current, you have to have the current and voltage used in the current. Then you would divide the voltage by the current to the number of ohms used (aka resistance)

Explanation:

Answer 2

Explanation:

Electric current

The flow of electric charge through any cross section of conductor in a unit time is called as electric current

SI Unit of current is ampere

ohms law state that the potential difference across the ends of the resistors is directly proportional to the current through it when temperature remains constant

V=RI
