Capacitance diagram for Q27 - JEE Main 2026 Evening
Circuit diagram showing a 5 microfarad capacitor connected in parallel with branches containing resistors and diodes.

Solution & Explanation

### Related Formula Q = C V_c where V_c is the steady-state voltage across the capacitor. ### Core Logic In steady state, the capacitor acts as an open circuit (blocks DC current). We must analyze the active branches.

Circuit diagram showing a 5 microfarad capacitor connected in parallel with branches containing resistors and diodes.
The branch with the reversed-biased diode will carry no current. Current flows through the outer loop via the forward-biased diode. Total active resistance R_texteq = 1\,Omega + 4\,Omega = 5\,Omega. Current in the steady state: i = fracVR_texteq = frac2.55 = 0.5 text A ### Step 1: Voltage Calculation The voltage across the capacitor V_c is equal to the voltage drop across the 4\,Omega resistor, because the branch is connected in parallel. V_c = i times 4\,Omega V_c = 0.5 times 4 = 2 text V ### Step 2: Final Conclusion The charge stored is: Q = C V_c Q = 5\,mutextF times 2text V = 10\,mutextC ### Pattern Recognition Capacitor in steady-state DC = open wire. Analyze only the paths where current can physically flow, check diode polarity, find nodal voltage across the capacitor terminals, apply Q=CV. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Physics: Electrostatics Class 12 Physics: Current Electricity Class 12 Physics: Semiconductor Electronics
