Answer #1

The charge stored in a capacitor

voltage in the capacitor at initially charged

voltage in the capacitor after the discharge

The formula for the voltage across a capacitor while discharging

substituting the values in the above equation

so the capacitor took 34.56s to reduce to 15micro C
