Alright — let's do this.
The energy (E) stored in a capacitor is given by the formula:
E=21CV2
where:
- C is the capacitance in Farads (F)
- V is the voltage across the capacitor in Volts (V)
Step 1: Identify the given values.
- Energy (E) = 8×10−2 J
- Voltage (V) = 100 V
Step 2: Rearrange the formula to solve for capacitance (C).
C=V22E
Step 3: Substitute the given values into the rearranged formula.
C=(100V)22×(8×10−2J)
C=1000016×10−2
C=100000.16
C=0.000016F
Step 4: Convert the capacitance from Farads to microfarads (μF).
Since 1F=106μF:
C=0.000016×106\muF
C=16\muF
The final answer is A)16\muF.
