I have been in my physics crash course for my entrance exam. I was looking at the chapter "Units and Measurement". I got a doubt in this chapter and I didn't get it cleared by my teacher. So I am posting this in this forum. We have 7 fundamental quantities and other quantities are derived quantities.In those fundamental quantities,We have (CURRENT)and its unit is A. but according to the definition. CURRENT is defined a rate of charge flowing across a cross sectional area of a conductor. and the formula is I=q/t. This looks like a derived quantity because t is a fundamental quantity. It is used in the formula. MY QUESTION IS WHETHER CURRENT IS A FUNDAMENTAL OR DERIVED QUANTITY??
