Hey There!!
Two capacitors, 0.5 and 0.75 are connected in parallel across a 110 V battery.
Our data is:
For two capacitors in parallel, the equivalent capacitance is given by:
Now, Charge from Source can be calculated as follows:
Here, tot simply represents the total amount of charge from source (i.e. battery).
Now, we know the total charge from source.
In a parallel connection, the potential across each capacitor is same.
Also, we have the formula
Since we know that V will be constant, we see that Charge on each capacitor is directly proportional to its capacitance.
That is,
The total charge from source is going to be divided among the two capacitors. We can write:
Now, we also know the charge on the first capacitor.
We also know that the charge from the source is divided among the two capacitors. So, we can write:
Thus, we can summarize the answers as follows:
Charge from source = 1.375
Charge on 0.5 capacitor = 0.55
Charge on 0.75 capacitor = 0.825
