Slove this question according to figure 04.
(a) Let current I flow in resistor as no current will flow in resistor due to open.
By KCL at node b
Current in S resistor ,so By KCL in loop
(b) First we have to find Rth (thevenin equivalent seen from b-c node) for this short voltage source and open current source.
As is open so not take part
So, therenin equivalent current for maximum power transfer
(c) As for maximum power
So, maximum power transfer to
