Question

Remember that the definition of an ampere is:1 Ampere = 1 Coulomb/secondAnd remember that its electrical charge is +e per proton.Their produced current was 1 microAmp = 1μA = 1 × 10−6 A.Using proportions, that’s enough information to calculate how many protons per second they were able to generate.

Answer 1

ANSWER:

6.25*10^12 protons per second

STEP-BY-STEP EXPLANATION:

We have that the electric charge of a proton is the following:

$p=1.6\cdot10^{-19}C$

We know that the current I is equal to 1 microampere, therefore we can calculate the number of protons in this charge as follows:

$\begin{gathered} 1\mu A\cdot\frac{10^{-6}A}{1\mu A}=10^{-6}A=10^{-6}\frac{C}{s} \\ \text{ therefore:} \\ 10^{-6}\frac{C}{s}\cdot\frac{1\text{ proton}}{1.6\cdot10^{-19}C}=6.25\cdot10^{12}\cdot\frac{\text{ protons}}{s} \end{gathered}$

Therefore, there is a flow of 6.25*10^12 protons per second
