Understanding Source Impedance
When dealing with electrical circuits, the source impedance can significantly affect power transfer. In this case, we have an inductive source impedance.
Inductive Source Impedance Characteristics
- An inductive impedance (Z = R + jXL) has a positive imaginary component (XL > 0).
- This leads to a phase shift where the current lags behind the voltage.
Maximum Power Transfer Theorem
For maximum power transfer from a source to a load, the load impedance (ZL) should ideally match the complex conjugate of the source impedance (ZS).
Complex Conjugate Matching
- If the source impedance is inductive, its complex conjugate will be resistive and capacitive (e.g., ZS = R + jXL, then ZL = R - jXL).
- Therefore, to offset the inductive reactance, a capacitive load is required since it introduces a negative imaginary component.
Why Choose Capacitive Load?
- A capacitive load (ZL = R - jXC) cancels out the inductive reactance of the source.
- This results in a purely resistive overall impedance, allowing maximum power transfer.
Conclusion
Thus, for a source with inductive impedance, using a capacitive load achieves maximum power transfer by balancing the reactive components. Therefore, the correct answer is indeed option 'A' - the load should be capacitive.
