Formula to find out the capacitance when we know the pd across the capacitor and the charge stored : |
C=Q/V |
|
|
Is the charge stored on a capacitor proportional to the pd across the capacitor? |
Yes |
|
|
How to find out the energy transferred just as the charge crosses the main supply? |
W =Q×V |
|
|
How to find out the energy stores in the capacitor? |
W=1/2 ×Q× V W=1/2× C × V^2 W=Q^2/ 2C |
|
|
Capacitors in parallel- |
• the pd across each capacitor is same • the total charge is the sum of the charge on individual capacitors • the total capacitance is the sum of the two capacitances, C=C1 + C2 |
|
|
Capacitors in series: |
• the charge on each capacitor is the same • the pd is shared between the two capacitors • the combined capacitance is 1/C= 1/C1 +1/C2 |
