Question

How much energy would each coulomb of charge from a 9volt battery possess?

Answer 1

Charge of one electron is $=1.6×10^{−19}C$

Thus 1 Coulomb has $6.26\times10^{18}$ Electrons.

Thus with 9 volt battery the energy on each coulomb of charge is $=9\times 6.25\times10^{18} \newline$

Energy=$5.625\times10^{19} eV$
