For the network shown in Fig., evaluate the current I flowing through the 2Ω resistor using superposition theorem.

A Delta-connected network with its Wye-equivalent is shown in Fig.P2.4. The resistance R₁, R₂ and R₃ (in ohms) are respectively

Identify which of the following is NOT a true of the graph shown in Fig.

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