What is the charge, Q, on the charged capacitor (in terms of C and V)?vipulsilwal said:Homework Statement
2 capacitors of equal capacitance one charged to potential V, and other completely discharged. when the are connected in parallel what would be the potential of each one of them.
Homework Equations
E=1/2 (C.V^2)
The Attempt at a Solution
as they are connected in parallel potential of each wud be same... now by conservation of energy i got answer V/sqrt(2)
am i right??
To solve for the potential of each capacitor in parallel, you need to first determine the total capacitance of the circuit. This can be done by adding the individual capacitances of the capacitors. Then, use Ohm's Law (V=IR) to calculate the total current flowing through the circuit. Finally, use the equation V=Q/C to calculate the potential of each capacitor, where Q is the charge on each capacitor and C is the individual capacitance.
Yes, you can use Kirchhoff's Laws to solve for equal capacitors in parallel. Kirchhoff's Laws state that the sum of all currents entering a node is equal to the sum of all currents leaving the node. This can be applied to parallel circuits by considering the total current flowing into the node and the individual currents flowing through each capacitor.
Yes, you need to know the individual capacitance values to solve for equal capacitors in parallel. The total capacitance of the circuit is dependent on the individual capacitance values, and without this information, you cannot accurately calculate the potential of each capacitor.
When equal capacitors are connected in parallel, the potential of each capacitor will be the same. This is because parallel capacitors have the same voltage across them, and according to Kirchhoff's Laws, the potential difference across each capacitor in a parallel circuit is equal to the total potential difference of the circuit.
No, the method for solving for equal capacitors in parallel is not suitable for solving for unequal capacitors in parallel. This is because the total capacitance and total current in the circuit will be different for unequal capacitors, and the potential of each capacitor will not be the same. In this case, a more complex calculation involving the individual capacitance values and the voltage divider rule must be used.
