Find total energy stored in capacitors given in the circuit

capacitors in series=

Capacitors in parallel= 1+1=2

Then, total energy stored in capacitors given in the circuit is given by

Where, E is total energy stored in capacitors, C is capacitance and V is potential difference across it.

Thus, the total energy stored in capacitors given in the circuit is.

From the information of energy band gaps of diodes, how do you decide which can be light emitting diodes?

Give any one advantage of LEDs over conventional incandescent low power lamps.
