2 Sketch the network graph if the incidence matrix is as represented below: (5)

3 A resistance R and 5uF capacitor are connected in series across a 100% ‏عل‎ (5)
supply. Calculate the value of R such that the voltage across the capacitor
becomes SOV in 5s after the circuit is switched on.

4 In an RL series circuit, R=5 Q, L=2.5mH and i(0°)=2A. If a source of 509 is (5)
applied at t=0, find i(t) for ‏,0ئ‎ using Laplace transformation.

5 For the network shown in figure 2, determine the transfer function 221(5) and the (5)

driving point admittance function Y11(s).
