Question

What does $50\mathrm{\mu F}$ mean on a capacitor?

Answer 1

1. A capacitor is a two-terminal electrical device that possesses the ability to store energy in the form of an electric charge.
2. The mathematical relation of capacitance and potential difference:
   $$\begin{gathered} \mathrm{charge}=\mathrm{capacitance}\times \mathrm{potential}\mathrm{difference} \\ \mathrm{Q}=\mathrm{CV} \end{gathered}$$
3. ${\text{1 micro Coulomb = 10}}^{-6}\mathrm{Coulomb}$
   $1\mathrm{\mu C}={10}^{-6}\mathrm{C}$
4. ${\text{1 micro Farad = 10}}^{-6}\mathrm{Farad}$
   $1\mathrm{\mu F}={10}^{-6}\mathrm{F}$
5. The $1\mathrm{C}$ amount of charge that passes through $1\mathrm{Volt}$ potential difference creates $1\mathrm{F}$ capacitance.
6. $50\mathrm{\mu C}=50\times {10}^{-6}\mathrm{C}$charge passes through $1\mathrm{Volt}$ potential difference and creates $50\mathrm{\mu F}$ capacitance.
