Question

One ampere Current is given by ____
A) 1A =1C/1ohm

B) 1A =1C/1s

C) 1A = 1s * 1C

D) 1A =1s/1C

Answer 1

One ampere Current is given by
B) 1A =1C/1s

Answer 2

Option (B) is correct.
One ampere current is given by:
1A = 1C / 1S
where 'C' is the unit of electric charge and 's' is the unit of time.
One ampere is defined as the current that flows with electric charge of 1 coulomb per second.
Ampere or amp is the unit of electrical current. It is represented by the symbol 'A' . The ampere unit is named after French mathematician and physicist Andre-Marie Ampere. 
Hope it helps. Thanks.
