Q31 neet_2024_05_may_morning Energy Loss in Capacitors
Consider two uncharged capacitors of equal capacitance 200 pF. One of them is charged by a 100 V supply and disconnected. Now this capacitor is connected to the uncharged capacitor. The amount of electrostatic energy lost in the process is:
  • A. 1.0 × 10⁻⁶ J
  • B. 0.5 × 10⁻⁶ J
  • C. 0.5 J
  • D. 1.0 J

Solution

Related Formula
Δ U = (1)/(2) (C₁ C₂)/(C₁ + C₂) V²
Core Logic

Given C₁ = C₂ = 200 pF = 200 × 10⁻¹² F, V = 100 V.

Δ U = (1)/(2) ((200 × 200)/(400)) × 10⁻¹² × (100)² = 0.5 × 10⁻⁶ J
Pattern Recognition

Standard energy loss formula when connecting charged to uncharged capacitor.
