capacitors in parallel

Question

Three capacitors of 2 μF, 3 μF, and 5 μF are connected in parallel. What is the equivalent capacitance?

1. **Parallel Rule**: Capacitors in parallel offer multiple paths for current, essentially increasing the effective plate area.
   - Formula: $C_{eq} = C_1 + C_2 + C_3 + \dots$
2. **Calculation**:
   - $C_{eq} = 2 	ext{ } \mu	ext{F} + 3 	ext{ } \mu	ext{F} + 5 	ext{ } \mu	ext{F} = 10 	ext{ } \mu	ext{F}$.
3. **Voltage Property**: In parallel, all capacitors experience the **same** potential difference $V$.
4. **Energy Check**: Since capacity increased, for the same voltage, more total energy is stored compared to individual components.
