本题目来源于试卷: Particulate Nature of Matter B.5 Electric Circuits，类别为 IB物理学

[单选题]
A circuit is connectedovumr50ks/ 0xw5pb *i across a p7w6jjoc svti u3/)a4$12\,V$ battery which provides $60\,J$ of electrical energy per second.
What is the rate of charge flow across the conductor?

A. 5$A$
B. 12$A$
C. 60$A$
D. 720$A$


参考答案:  A


本题详细解析:

$60 \,J$ per second gives power, $P=60W$

$I=\frac{P}{V}=\frac{60}{12}​=5A$ therefore the answer is $A$.
