Topic: Network Theory
According to maximum power transfer theorem, maximum power transfer occurs when
- A. Load R is equal to the half the R of network
- B. Load R is equal to twice the R of network
- C. Load R is equal to the R of network looking back at it from voltage terminal
- D. Load R is equal to the R of network looking back at it from load terminals with all sources being replaced by their respective internal resistance
Answer: D. Load R is equal to the R of network looking back at it from load terminals with all sources being replaced by their respective internal resistance
Explanation: The Maximum Power Transfer Theorem states that maximum power is delivered to a load when the load resistance equals the Thevenin equivalent resistance of the network, which is the resistance looking back from the load terminals with all independent sources replaced by their internal resistances.
