Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a capacitor with a capacitance of 22μF charged to 12V. If the voltage is doubled, what happens to the stored energy?

💡 Hint: Follow the energy formula carefully.

Challenge 2 Hard

A capacitor charged to 20V is disconnected from a battery and then connected to an uncharged capacitor of same capacitance. What will be the final voltage?

💡 Hint: Remember charge conservation and capacitance properties.
