You need the capacitor to store 60.7 mJ of energy when a 26.5 V battery is connected between terminals A and B for a long time. Then to discharge half of this stored in energy in exactly 3.80 seconds when the battery is removed and replaced by a 23500 load bat you need the capacitor Determine the ideal values for the capacitor and resistor such that your circuit wil achieve these design goals Number C,172.87 Number R45000 Incorrect Previous# Try Again extEl ExitSubmit Assignment Explanation

Explanation / Answer

energy become half when charge becomes 1/sqrt2 times

in discharing we know that

Q = Q0 e^-t/RC

Q = Q0/sqrt2

1/sqrt2 = e^-t/(R1+RL)C

R1 = 39926 ohm ( any doubt comment below)
