EE40 Spring 2008 Homework 2 Due Friday 2/8 5 p.m. sharp. No extensions! 1) Find the equivalent resistance between the terminals a and b for the following networks: a) 4Ω 3Ω6Ω8Ω2Ω2Ωbda2ΩC2Ω3Ω b) Same network as above, except that there is also a short circuit between nodes c and d. 2) Hambley P 2.17 3) Hambley P 2.24 4) Hambley P 2.32 5) Hambley P 2.49 6) Hambley P 2.52, except that you should choose as the reference the node where the 2 Ω and 10 Ω resistors and the current sources meet. Find the graph of the circuit, choose a tree that contains the voltage source, and use a supernode. 7) Solve for the node voltages v15ΩC3A1A1A5ix10Ω20Ωixv28) Hambley 2.64 9) Hambley 2.72. First find the graph of the circuit, and then choose a tree that does not contain the current source, before starting mesh analysis. 10) Hambley
