Question

Define electric current.What is the SI unit of electric current.​

Answer 1

Answer:

Electric current is basically the flow or charge of the electric charge in motion in a conductor. It is said to exist when there is a net flow of charge through the region. the current is given as the flow of charge per second: I=timecharge. The SI unit of current is Ampere.

please mark me as brainliest answer and give thanks

Answer 2

Answer:

Electric current is the charge or flow of electrons in a wire from positive to negative end.

SI unit of electric current is Ampere. Denoted by letter "A".

Explanation:

Suppose 2 long straight wires with negligible cross-section are placed parallel to each other in vacuum at a separation of 1m& electric currents are established in the 2 in same direction. The wires attract each other. If the equal currents are maintained in the 2 wires so that the force between them is 2×10^-7 Newton per meter of the wires,the current in any of the wires is called 1A.

Here,Newton is the SI unit of force...
