Question

The potential across a $25.0$ microfarad capacitor is $5.0V$.What is the charge on the capacitor?

• A. $0.20$ microcoulombs
• B. $5.0$ microcoulombs
• C. $125$ microcoulombs
• D. $30.0$ microcoulombs
• E. We cannot determine the charge on the capacitor with the given information

Answer 1

The correct option is C $125$ microcoulombs

Potential difference across the capacitor $V=5.0$ V

Capacitance of the capacitor $C=25.0$ $\mu F$

Charge on the capacitor $Q=CV=25.0\times 5.0=125$ $\mu$C
