What equation represents the maximum energy-transfer condition?

• A. R(load) = R(source)
• B. Lenz's law
• C. Z(load) = Z*(load)
• D. V(Phase) = V(Line)/√3

Answer: (C)

The maximum energy-transfer condition in an electrical system occurs when the load impedance matches the complex conjugate of the source impedance. This principle is key in maximizing the power transferred from the source to the load. Specifically, when the load impedance equals the complex conjugate of the load’s impedance, it ensures that the conditions are optimal for power transfer. By defining the load and source impedances in complex form, matching the load impedance, Z(load), to the conjugate of the source impedance, Z*(source), results in the maximum real power transfer. This is derived from the concept known as the "maximum power transfer theorem," which indicates that for a given network, the load must have an impedance that allows it to draw maximum power from the source. In the context of the choices provided, the specified condition in the correct answer encapsulates this optimal scenario effectively, leading to the maximum energy being transferred in the circuit. This principle is widely applied in electrical engineering, particularly in communications and power systems, to optimize performance. Other provided options do not pertain to the condition of energy transfer in relation to impedance: the matching of resistances or reactances outlined in those choices does not inherently lead to the maximum energy transfer as effectively as the matching of complex
