alleryOne ampere is defined as the current when
A$1\text{ J}$ of work is done in $1\text{ s}$
B$1\text{ C}$ of charge flows in $1\text{ s}$
C$1\text{ C}$ of charge flows in $1\text{ min}$
D$1\text{ A}$ of charge flows in $1\text{ s}$
Answer & Solution
Correct answer: B. $1\text{ C}$ of charge flows in $1\text{ s}$
By definition, $1\text{ A}=1\text{ C s}^{-1}$.
**So if $1\text{ coulomb}$ of charge passes a point in $1\text{ second}$, the current is $1\text{ ampere}$.**
