Energy Stored In Capacitor In Steady State

For finding energy stored in steady state the formula is 12 cvv where v is the steady state voltage across the capacitor. At steady state no current passes through the capacitors so current is isolated in upper and lower loops using kvl in them iupper1 ampere and ilower05 ampere then using kvl in loops with both capacitors gives 8v1v20 where v1v2 are potential across capacitors.

This will be the current through the first inductor.

Energy stored in capacitor in steady state. Replace the inductor with short circuit and the capacitor with open circuit. Draw the modified circuit. 1 28 3 and calculate the total stored energy.

Under steady state condition the inductor and the capacitor are full charged. You will get the v value ie voltage across the open circuited capacitor. The total energy stored in the circuit is the sum of the energy stored in elements capable of storing energy ie.

The voltage across the capacitor in steady state will be 5 volts so you know the energy in it. In a dc circuit in steady state capacitor acts as an open circuit. So energy stored in this circuit should be zero.

Now switch the sources as shown in fig. So 2 ohm 4 ohm and 2 ohm these three resistors are in series. Add them up to get the total energy in the circuit.

And resistor only dissipate energy. Recall that the energy stored in an inductor is and is equal to for a capacitor. In steady state condition capacitor should be replaced by open circuit.

The energy stored in the capacitor in the steady state is. So analyse the circuit using kvl with capacitor open circuited. Use the above mentioned equation to find energy stored.

Two capacitors and two inductors. Thus the total stored energy is. So total resistor is 8 ohm.
