Question

g A power amplifier has an output impedance of 47+j8Ω. It produces a no-load output voltage of 156 V at 300 Hz. Problem 11.096.a - Load impedance of a power amplifier Determine the impedance of the load that achieves maximum power transfer. The impedance of the load that achieves maximum power transfer is ( – j ) Ω.

Answer 1

47-j8Ω

Step-by-step explanation:

Maximum power transfer occurs when load impedance is matched with source impedance

Answer 2

The impedance load that achieves maximum power transfer is 47 - j8 Ω

Step-by-step explanation:

The Power Amplifier will have output impedance Zth = 47 + j8 Ω

Voltage V = 156 at 300 Hz

Impedance of the load will be given as Zl

Zl = Zth°

Zl = 47 - j8 Ω
