Unformatted text preview: Name: UM C# : UNIVERSITY OF MIAMI DEPARTMENT OFHELECTRICAL COMPUTER ENGINEERING L L L 7 ' ' EEN 201 —— ELECTRICAL CIRCUIT THEORY Final Examination (Fall 2007) Attempt all problems. Show all work. The use of books or notes are not allowed ' Total: 100 points. 1. Use nodal analysis to ﬁnd V0 in this network. Show all steps of the solution: 12/12/2007 MSS 2. Determine i0(t) for the network in the ﬁgure below. Plot this current for -0.5 s < t < 0.5 s. v 6n 3. For the circuit shown below determine the value of the load impedance ZL so that maximum power is delivered to it, and compute that power. 4. An industrial load is supplied through a 60~HZ transmission line which has line impedance of 0.1 + j0.2 Q. The voltage at the load terminals is 480 Vrms (angle = O). The load consumes 124 kW at power factor of 0.5 lagging. What should be the value of a capacitor placed in parallel withthe load which would change thepowergfactorrto lagging? ...
