Question

2.5 into 10 to the power 18 electrons flow through a copper wire in one second. the current flows through the conductor is​

Answer 1

Answer:

So a current of 4 amp flows through the copper wire

Explanation:

We have given that $2.5\times 10^{18}electron$ flows through the copper wire in 1 sec

So number of electrons $n=2.5\times 10^{18}$

We know that charge on electron $e=1.6\times 10^{-19}C$

We know that charge flow is given by $q=ne=1.6\times 10^{-19}\times 2.5\times 10^{18}=4C$

Time is given by t = 1 sec

Current is given by $i=\frac{q}{t}=\frac{4}{1}=4A$

So a current of 4 amp flows through the copper wire

Answer 2

Answer: current flowing through the conductor is 0.4 ampere
