Consider two capacitors with capacitance 2µF and 4µF. With which type of connection will the 4µF capacitor have a greater amount of stored energy than the 2µF capacitor?
Correct answer: B. Parallel
- A. Series
- B. Parallel
- C. Either series or parallel
- D. Neither series nor parallel
Explanation
Option A) Series and Option C) Either series or parallel are not correct because in a series connection, the 4uF capacitor will have a smaller amount of stored energy than the 2uF capacitor because it has a smaller capacitance.Option B) This is because the capacitance in parallel circuits is greater.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
