Show hintHide hint
Use the capacitance formula with the dielectric constant.
Question 6.
If a capacitor has a plate area of 0.2 m², distance of 0.02 m, and a dielectric constant of 4, calculate the capacitance and the stored energy if a voltage of 100 V is applied.
Show hintHide hint
Use both capacitance and energy formulas.
