The equivalent circuit of Figure P3.57 has Vt = 35 V and Rt = 600 ohms. If the conditions for maximum power transfer exist, determine the value of RL, power of RL, and efficiency of the circuit.
See diagram in attached file.
Maximum power transfer will occur if Rt = RL (from Maximum Power Transfer Theorem).
Thus RL = 600 ohms.
This solution looks at the efficiency and power of a circuit.
