A conductor carries a steady current and 30 C of charge flows past a point in 6 seconds. What is the current?
A5 A
B0.2 A
C36 A
D180 A
Answer & Solution
Correct answer: A. 5 A
1. Current is the rate of flow of charge: $I = \dfrac{Q}{t}$.
2. Substitute $Q = 30\,\text{C}$ and $t = 6\,\text{s}$.
3. $I = \dfrac{30}{6} = 5\,\text{A}$.
