Electric current...... Electrical engineering, electricity, BCDP

 Current is the flow of electrons 

SI unit - Amperes (A) 

Other units - mA - Milli Amperes 

1A= 1000mA

1mA = 1/1000A

Electric current (I) = V/R 

Electric current= Charge / Time 

Electrons are negatively charged they flow from the negative terminal to the positive terminal 

But 

Conventional current or electric current flows from positive to negative 

This is the opposite flow get more about here
