Dr. Nina Telaug Exam # 2
Name: You will spend the ﬁrst 15 minutes discussing this exam with your team.
During this time you will not use your calculator or pen/pencil. The sole
purpose of the team exercise is brainstorming. Read the entire exam ﬁrst. Box all ﬁnal answers or write them in the space provided.
Remember to provide correct writs for all quantities.
Show all your work. Extra paper is available. Be neat — I need to be able to read your work. Aim for an A+ Relax!!! © HPMFP‘PT‘ I Problem # 1 I 0 Problem # 2 0 Problem # 3 ‘ a ’1  Problem # 4 "W I Problem # 5 L

with the dependent source. [20 points] 15A Nodal Analysis 2. Using nodai analysis ﬁnd the voltage across the dependent source. Mark the
polarity of the voltage on the schematic. Calculate the power associated with this
source. Is this source absorbing or delivering? [20 points]  KM

(i) The voltage across the 5 (1 resistor due to the 110 V source.
(ii) The current through the 5 ﬂ resistor due to the 110 V source.
(iii) The total voltage across the 5 ﬂ resistor due to all sources.
(iv) The total voltage across the 5 Q resistor when the voltage source is
changed to 55V. [20 points]
