A 5 uf capacitor has 5x10 coulombs a charge stored in its plates find the voltage across the capacitor?

Q=CV, with Q=(5x10) = 50 Coulombs, and C=5x10^-6 Farads,

therefore: 50 = 5x10^-6 x V

V = 50 / (5x10^-6) = 10,000,000 Volts.

Seems like rather a lot! Maybe there's a typo in the question? Either way, use Q=CV to give the right answer.

is this right seems rather high to (50 volts?)
