What is the maximum energy that can be stored in a capacitor?(a) Depends on the maximum area of the capacitor(b) Depends on the maximum resistance offered(c) Depends on the maximum electric field(d) Depends on the maximum current passing through the capacitorThis question was addressed to me during an online interview.I'd like to ask this question from Energy Stored in a Capacitor in section Electrostatic Potential and Capacitance of Physics – Class 12

Answer»

Correct ANSWER is (C) Depends on the MAXIMUM electric field

Easiest explanation: The maximum energy that can be desirably stored in a CAPACITOR is depends on the maximum electric field that the DIELECTRIC can withstand without breaking down. Therefore, capacitors of the same type have about the same maximum energy density, i.e. joules of energy per cubic meter.
