Use nodal analysis to find node voltages V1, V2 and V3. R;=100, R2=60, R3=70, Ra=40, k=2A, I2=1A. Hint : After you got equations for each node, you can solve using Matrix (with the help of calculator), or with elimination/substitution method. V1 R V2 R2 V3 12 R3 R4

2. For the circuit shown below, determine the voltage across R2. _V1 -30 V R1 100 R3 100 R2 50 R4 {50 11 16 A

Find the i_norton and r_th from node a to b using Norton equivalents using the values in the circuit.

What are the node voltages values in the circuit below. Express answers with or without (20 or 20 V). Fractional values to four significant digits after the decimal using truncation (0.234531 as 0.2345).  Find V1, V2, V3, and V4. V1 = _ V V2= _ V V3= _ V V4= _ V
