Find the ratio between the energy stored in 5 μF capacitor to the�

1.	Find the ratio between the energy stored in 5 μF capacitor to the 4 μF capacitor in the given circuit in steady state?
Answer» In steady state , the capacitors are fully charged and no current pass through them. So no current also pass through resistors 4 ohm and 5 ohm. Thus, the potential across the capacitors will be 2V. Energy stored in 5μF capacitor is U₅= 1/2 × 5 × 2²= 10J Energy stored in 4μF capacitor is U₄= 1/2 × 4 × 2²= 8J Thus, U₅/U₄= 10/8 = 5/4

Answer»

In steady state , the capacitors are fully charged and no current pass through them. So no current also pass through resistors 4 ohm and 5 ohm. Thus, the potential across the capacitors will be 2V.

Energy stored in 5μF capacitor is U₅= 1/2 × 5 × 2²= 10J

Energy stored in 4μF capacitor is U₄= 1/2 × 4 × 2²= 8J

Thus, U₅/U₄= 10/8 = 5/4
