To find the loss of energy due to parallel connection of capacitors, we need to calculate the initial energy stored in each capacitor and the final energy stored in the parallel combination of capacitors.
Given:
Capacitor C1 has a capacitance of 2F and is charged to a voltage of 100V.
Capacitor C2 has a capacitance of 4F and is charged to a voltage of 50V.
1. Calculate the initial energy stored in each capacitor:
The energy stored in a capacitor can be calculated using the formula: E = (1/2) * C * V^2, where E is the energy, C is the capacitance, and V is the voltage.
For capacitor C1:
E1 = (1/2) * 2 * (100^2) = 10,000 J
For capacitor C2:
E2 = (1/2) * 4 * (50^2) = 5,000 J
2. Calculate the total initial energy before connecting the capacitors in parallel:
Total initial energy = E1 + E2 = 10,000 J + 5,000 J = 15,000 J
3. Calculate the final energy stored in the parallel combination of capacitors:
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. In this case, C_total = C1 + C2 = 2F + 4F = 6F.
The final voltage across the capacitors when connected in parallel is the same as the initial voltage across each capacitor, which is 100V.
The energy stored in the parallel combination of capacitors can be calculated using the formula: E_total = (1/2) * C_total * V^2.
E_total = (1/2) * 6 * (100^2) = 30,000 J
4. Calculate the loss of energy due to parallel connection:
Loss of energy = Total initial energy - Final energy stored
Loss of energy = 15,000 J - 30,000 J = -15,000 J
Since energy cannot be negative, the loss of energy due to parallel connection is 15,000 J.
Therefore, the correct answer is option 'B' - 1.7101 J.
