Characteristic of capasitor -Can save electric energywithout chemistryreaction-Cant be passed by DC

electric current, but canbe passed easily by ACelectric current-If it is related withdifferent electric

potential, each platecarries equal amount ofcharge. One plate carriespositive charge and theother caries negativecharge.

A capasitor consist of two parallelconducting plate, each of area A,that separated by dielectricmaterial/isolator/ vaccum

Between two plate are related withdifferent electric potential V.Each plate carries equal amount of

charge. One plate carries positivecharge and the other cariesnegative charge.

1. Capasitance of capasitor (C g ),

Capasitance of 1 st capasitor (C 1),Capasitance of 2 nd capasitor (C 2) is:

2. The charge that is kept in circuit= thecharge in each capasitor.Q = Q 1 + Q 2 dan Q 1 = Q 2

3. Electric potential(V), potential at 1 st capasitor (V 1 ) and 2 nd capasitor (V 2 )is:V = V 1 + V 2

Example:

1. Kapasitance of capasitor :

C g = 6/5 = 1,2 F

2. The charge in the circuit= 1,2 F x 6V = 7,2 C1 st capasitor = 7,2 C2nd capasitor = 7,2 C

3. Electric potential:1 st capasitor = 3,6 V2nd capasitor = 2,4 V

1) Potential at 1 st capasitor (V 1), 2 nd capasitor (V 2) and at the sourcepotential (V) is V 1 = V 2 = V

2) The charge that is kept in the circuit isQ = Q 1 + Q 2

3) Capasitance of union of capasitor is:Cg = C 1 + C 2


11/16

Paralel Circuit 1. Each capasitor has samepotential, then we getV1 = V2 = 6 volt

2. Capasitance of capasitor is

C g = C 1 + C 2 = 2 F + 3 F = 5 F

3. The charges that are kept in thecircuit are:Q = C g xV = 5 F x 6V = 30 C

Q1 = C 1 x V = 2 Fx6V = 12 CQ2 = C 2 x V = 3 Fx6V = 18 C
