थेवेनिन का प्रमेय (Thevenin's theorem) कड़ाई से निम्नलिखित में से किस नेटवर्क प्रकार पर लागू होता है? I) रैखिक नेटवर्क (Linear Networks) II) गैर-रैखिक नेटवर्क (Non-linear Networks) III) समय परिवर्तक नेटवर्क (Time Variant Networks)

While calculating Thevenin resistance (Rth) or Norton resistance (RN), independent constant current sources in the circuit are:

While calculating Thevenin resistance (Rth), constant current sources in the circuit are:

According to the Maximum Power Transfer Theorem, maximum power is delivered from a source to a load when the load resistance (RL) is equal to the internal resistance (r) of the source. At this specific condition, what is the efficiency of the power transfer?
