JEE Main 2022 Physics question
A capacitor is discharging through a resistor R. Consider in time , the energy stored in the capacitor reduces to half of its initial value and in time , the charge stored reduces to one eighth of its initial value. The ratio will be
Answer: (4)
Solution
The energy is proportional to , so when the energy falls to half the charge becomes of its initial value: (1/ = t_{1}$/τ
