Question

If this combination of capacitors is attached to a 9 v battery how much energy will be stored on the plates 25 15

Answer 1

The energy stored on the plates will be 378.5 J. The combination of capacitors is in series.

What is a capacitor?

A capacitor is a device that can store electrical energy. It is a two-conductor configuration separated by an insulating medium that carries charges of equal size and opposite sign.

An electric insulator or vacuum, such as glass, paper, air, or a semiconductor termed a dielectric, can be used as the non-conductive zone.

The complete question is;

"If this combination of capacitors is attached to a 9.00 V battery; how much energy will be 25 μF 15 μF stored on the plates?"

If the two capacitors are in series the equivalent capacitance will be;

$\rm \frac {1}{C} = \frac{1}{C_1}+\frac{1}{C_2} \\\\ \rm \frac {1}{C} = \frac{1}{25}+\frac{1}{15} \\\\ C = 9.375$

Energy will be stored on the plates;

$\rm E = \frac{1}{2}CV^2 \\\\ E= \frac{1}{2} \times 9.375 \mu F \times ( 9 \ V)^2\\\\E = 378.5 \ J$

Hence the energy stored on the plates will be 378.5 J.
