The Correct Option is A
Solution and Explanation
Step 1: Apply nodal analysis at \(V_A\):
\[
\frac{V_A - 10}{\alpha} + \frac{V_A}{1} = 10.
\]
Simplify:
\[
\frac{V_A - 10}{\alpha} + V_A = 10.
\]
\[
(1 + \alpha)V_A = 10\alpha + 10.
\]
\[
V_A = 10.
\]
Step 2: Current through the \(10 \, \Omega\) resistor:
\[
I = \frac{10 - V_A}{\alpha} = 0 \, \text{A}.
\]
Step 3: Power delivered:
\[
P = 10 \cdot I = 0 \, \text{W}.
\]
Step 4: Since no current flows, the power delivered is zero.

Top Questions on Power
- The single line diagram of a lossless system is shown in the figure. The system is operating in steady-state at a stable equilibrium point with the power output of the generator being \( P_{max} \sin \delta \), where \( \delta \) is the load angle and the mechanical power input is \( 0.5 P_{max} \). A fault occurs on line 2 such that the power output of the generator is less than \( 0.5 P_{max} \) during the fault. After the fault is cleared by opening line 2, the power output of the generator is \( \frac{P_{max}}{\sqrt{2}} \sin \delta \). If the critical fault clearing angle is \( \pi/2 \) radians, the accelerating area on the power angle curve is \_\_\_ times \( P_{max} \) (rounded off to 2 decimal places).

The per-phase synchronous reactance of the generator is \( 30\Omega \). If the generator is producing the rated current at the rated voltage, then the power factor at the terminal of the generator is:

- A single-phase full-controlled thyristor converter bridge is used for regenerative braking of a separately excited DC motor with the following specifications: Rated armature voltage = \( 210 \, \text{V} \), Rated armature current = \( 10 \, \text{A} \), Rated speed = \( 1200 \, \text{rpm} \), Armature resistance = \( 1 \, \Omega \), Input to the converter bridge = \( 240 \, \text{V at 50 Hz} \).
