Calculating the Charging Voltage for a Capacitor

To calculate the voltage required to charge a capacitor to a specific energy level, we can use the formula:

E = (1/2) * C * V^2

Where: - E is the energy stored in the capacitor (1 J in this case) - C is the capacitance (10 µF in this case) - V is the voltage across the capacitor (what we want to find)

We can rearrange the formula to solve for V:

V = sqrt((2 * E) / C)

Substituting the given values: V = sqrt((2 * 1 J) / 10 µF)

Calculation

V = sqrt((2 * 1) / 10) = sqrt(0.2) ≈ 0.447 V

So, the voltage required to charge the 10 µF capacitor to have an energy of 1 J is approximately 0.447 volts.
