Answer:
1/2
Explanation:
The energy stored in a capacitor is given by
where
C is the capacitance
V is the potential difference
Calling the capacitance of capacitor 1 and
its potential difference, the energy stored in capacitor 1 is
For capacitor 2, we have:
- The capacitance is half that of capacitor 1:
- The voltage is twice the voltage of capacitor 1:
so the energy stored in capacitor 2 is
So the ratio between the two energies is
