An electric flash lamp has 20 capacitors each of capacitance 5uF connected in parallel. The lamp is operated at 100V. If the energy stored in the combination is completely radiated out in a single flash, how much energy will be radiated in a flash?

Three capacitors of capacitance 2pF, 3pF, and 4pF are in parallel a. What is the total capacitance of the combination? b. Determine the charge on each capacitor if the combination is connected to a 100V supply?

The plates of a parallel plate capacitor have an area (20 cm^2) each are separated by a distance of 2.5 mm. The capacitor is charged by connecting it to a 400V supply. How much electrostatic energy is stored in the capacitor?

An electric bulb has marking 110 V , 100W on it . How much energy is used per second by the circuit ?

In parallel plate capacitor with air between the plates, each plate has an area of 6 xx 10^3m^2 and the distance between the plates is 3mm. Calculate the capacitance of the capacitor if it is connected to 100V supply.What is the charge on each plate of the capacitor?
