Capacitor 2 has half the capacitance and twice the potential difference as capacitor 1.what is the ratio uc1/uc2.

1/2

Explanation:

The energy stored in a capacitor is given by:

where

C is the capacitance

V is the potential difference

For capacitor 1, we have

Capacitor 2 has

(half the capacitance of capacitor 1)

(twice the potential difference of capacitor 1)

So the energy of capacitor 2 is

So, the ratio between the two energies is

their crystal patterns have been disrupted by stress

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
