Correct Answer - Option 2 : maximum power is transferred to the load
Maximum power transfer theorem:
Maximum power transfer theorem states that " In a linear bilateral network if the entire network is represented by its Thevenin's equivalent circuit then the maximum power transferred from source to the load when the load resistance is equal to the Thevenin's resistance.
- If source impedance is complex then load impedance has to be a complex conjugate of source impedance for maximum power transfer to occur.
- Maximum efficiency is not related to maximum power transfer.
- If the source and load impedances are matched then there are no reflections but maximum power transfer.
Properties of maximum power transfer theorem:
- This theorem is applicable only for linear networks i.e networks with R, L, C, transformer, and linear controlled sources as elements.
- The presence of dependent sources makes the network active and hence, MPPT is used for both active as well as passive networks.
- This theorem is applicable when the load is variable.
