The electron charge

Question

 The electron charge is e- = -1.6x10^-19 C (coulomb), how many electrons in total charge of Q= -4.8 uC

Answer 1

 The electron charge is e- = -1.6x10^-19 C (coulomb), how many electrons in total charge of Q= -4.8 uC

1 uC is equivalent to 1 x 10^-6 C, so the conversion factor from uC to C is 10⁶ uC / 1 C .

As the given charge is -4.8 uC, the conversion to C is 1C / 10⁶ uC x -4.8 uC = -4.8 x 10^-6 C.

Now that we have the total charge in C, we can determine how many electrons are in that charge. The conversion factor for this is 1 e / -1.6 x 10^-19 C x -4.8 x 10^-6 C. = 3 x 10¹³ electrons.
