Energy in ParallelMediumQuestion 31530

Question

Capacitors 2 μF and 3 μF in parallel are charged to 10 V. Total energy stored is:
  1. A
    250 μJ
    Correct
  2. B
    125 μJ
  3. C
    500 μJ
  4. D
    100 μJ

Correct answer

250 μJ

Explanation

C_total = 5 μF. U = ½CV² = ½×5×10⁻⁶×100 = 250 μJ.
