Question

Assuming that the load impedance is to be purely resistive, what load should be connected to terminals a-b of the circuits in the given figure so that the maximum power is transferred to the load? Assume R = 52 Ω.

Options:

1. 100 Ω
2. -j10 Ω
3. 40 Ω
4. 120/60°

Also, it mentions something about v (+ 2/90 A j30 Ω o b, but it's not clear how it connects to the question. Please clarify.

Answer 1

The maximum power transfer theorem dictates that the load resistance should equal the circuit's Thevenin resistance for ideal power transfer. With a given resistance R of 52 Ω, the matching load resistance should also be 52 Ω, but this is not an available option in the choices provided.

Step-by-step explanation:

According to the maximum power transfer theorem, for maximum power to be transferred to a load, the load resistance should be equal to the Thevenin resistance of the circuit as seen from the load terminals. Given that the original resistance R is 52 Ω, the load that would result in maximum power transfer would be a purely resistive load with the same resistance value, 52 Ω. Unfortunately, this option is not listed among the provided choices, so with the information given, it is not possible to select an appropriate answer from the provided options. If a typo is responsible for the discrepancy, the ideal answer would be a 52 Ω load that is not listed, assuming a purely resistive circuit without Thevenin resistance modification and only considering the provided R value.
