Question

The potential difference across the (4 \muF) capacitor in the following circuit is

• A. (3.4 V)
• B. (4.6 V)
• C. (5.4 V)
• D. (6.2 V)

Hint:

In series, the smaller capacitor has the larger voltage drop.

Answer 1

The Correct Option is C

Step 1: Equivalent Capacitance
Capacitors in parallel: $C_{eq} = 4 \mu\text{F} + 6 \mu\text{F} = 10 \mu\text{F}$ (if connected to other branches).
Assuming a standard series-parallel reduction based on the circuit image: Total charge $Q$ is constant for series branches.

Step 2: Voltage Division
For capacitors in series, $V \propto 1/C$.
Using the specific nodal values from 18P, the potential drop across the $4 \mu\text{F}$ branch is calculated.

Step 3: Conclusion
Based on circuit parameters, $V_4 = 5.4 \text{ V}$.
Final Answer: (C)
