MCQ
+2 marks
-0.66 marks
The V-I characteristic as seen from the terminal pair (A,B) of the network of figure (a) is shown figure (b), if a variable resistance 
is connected across the terminal pair (A,B), the maximum power that can be supplied to would be
80W
40W
20W
Indeterminate unless the actual network is given
Explanation:
For maximum power, load resistance should be equal to the venin resistance.
From the characteristics shown,
Open Circuit Voltage, I = 0, 
Short Circuit Current, V = 0 
…………..(1)
…………..(2)
For maximum power transfer load resistance,
Power =
