Question

5) Three capacitors of capacitance
•1uF, 2 uF and 3uF are connected
in parallel (a)what is the ratio of charges? (b)what is the ratio of Potential
differences?
​

Answer 1

Given:

Three capacitors of capacitance of 1 uF, 2 uF and 3uF are connected in parallel.

To find:

• Ratio of charges ?
• Ratio if potential difference ?

Calculation:

• Whenever capacitors are connected in parallel combination, they experience same potential drop (or potential difference) across the plates of the capacitor. So, the ratio of potential difference will be 1 : 1 : 1.

Now, coming to charges :

• Charge across 1uF = 1V uC
• Charge across 2uF = 2V uC
• Charge across 3uF = 3V uC.

So, the ratio of charges will be 1 : 2 : 3.
