Question

A capacitor of capacitance 5 \(\mu\)F is charged to 100 V and then connected to an uncharged capacitor of 2 \(\mu\)F. What is the final potential difference across the capacitors?

• A. 71.43 V
• B. 50 V
• C. 28.57 V
• D. 100 V

Hint:

When capacitors are connected in parallel after one is charged, the final potential difference can be found using charge conservation. The total charge divides inversely proportional to the capacitances.
