The voltage \( V_o \) in the network shown is

Step 1: The given circuit involves diodes and a resistor. To calculate \( V_o \), use the diode equation and consider the threshold voltage for silicon diodes.
Step 2: The voltage drop across each diode is considered 0.7V for the forward-biased Si diode. The total voltage is split across the diodes, and the final voltage at \( V_o \) is determined by the supply voltage minus the drops.
Step 3: After calculating, the voltage at \( V_o \) is found to be 11.3V. Thus, the correct answer is option (1), \( V_o = 11.3 \) V.
The graph shows the variation of current with voltage for a p-n junction diode. Estimate the dynamic resistance of the diode at \( V = -0.6 \) V.

Assertion (A): We cannot form a p-n junction diode by taking a slab of a p-type semiconductor and physically joining it to another slab of an n-type semiconductor.
Reason (R): In a p-type semiconductor, \( n_e \gg n_h \) while in an n-type semiconductor \( n_h \gg n_e \).
Match the following physical quantities with their respective dimensional formulas.
