Question: Current of 4.8 amperes is flowing through a conductor. The number of electrons per second will be
[CPMT 1986]
Options:
A) $ 3\times 10^{19} $
B) $ 7.68\times 10^{21} $
C) $ 7.68\times 10^{20} $
D) $ 3\times 10^{20} $
Show Answer
Answer:
Correct Answer: A
Solution:
Number of electrons flowing per second $ \frac{n}{t}=\frac{i}{e} $
$ =4.8/1.6\times {{10}^{-19}}=3\times 10^{19} $
