Are the invertors used in our houses are a type of capacitors?
Asked by Alekhya K | 01 Jun, 2014, 10:50: AM
answered-by-expert Expert Answer
Appliances in our homes work on a.c. power. During a power failure, an inverter is used to run the appliances.
Inverter is a circuit containing battery, transformer and switch and it converts the d.c. into a.c.
Hence, inverter is just a battery and not a type of capacitor as capacitors store charge and inverter does not.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
