Use the data of Fig.(a). The current i in the circuit of Fig.(b) is

The value of R (in ohms) required for maximum power transfer in the network shown in Fig. is

The Thevenin equivalent voltage V_TH appearing between the terminals A and B of the network shown in Fig. is given by

A DC circuit shown in the figure has a voltage source V, a current source I and several resistors. A particular resistor R dissipates a power of 4 Watts when V alone is active. The same resistor R dissipates a power of 9 Watts when I alone is active. The power dissipated by R when both sources are active will be
