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.
Sliding contact of a potentiometer is in the middle of the potentiometer wire having resistance \( R_p = 1 \, \Omega \) as shown in the figure. An external resistance of \( R_e = 2 \, \Omega \) is connected via the sliding contact.
The current \( i \) is :
If the curves $$ 2x^2 + ky^2 = 30 \quad \text{and} \quad 3y^2 = 28x $$ cut each other orthogonally, then \( k = \)
