A 10 nF capacitor is charged to 5 V. How much charge does it store?

Q = C*V = 10*10^-9F * 5V = 50*10^-9

Coulombs.

To find out how much charge a capacitor stores, you need to use the formula Q = C × V, where Q represents the charge, C represents the capacitance, and V represents the voltage across the capacitor.

In this case, the capacitance (C) is given as 10 nF, which is equivalent to 10 × 10^(-9) Farads, and the voltage (V) is given as 5 V.

Let's plug these values into the formula:

Q = C × V
= (10 × 10^(-9) F) × (5 V)

Calculating this expression will give us the value of charge (Q).
