Question
For the circuit of Figure 11-49(b): Find the supply current. Find the 3 K Ohm resistor current and voltage drop. Find the node voltages Va Vb, and Vf. Find the voltage differences Vaf, Vab, and Vbd. Find the supply current if the 12 K Ohm resistor is shorted out. Find the supply current if the 12 K Ohm resistor is opened.Explanation / Answer
total resistance=1+6+(4+1)=12k a)v=ir ==>i=(36+36)/12 ===>i=6 milli ampere b)i'=6 *(12/8)/(12/8 +3) =2 mili ampere v'=2*3=6 volts c)va=36volts vb=36-1(6)=30volts vf=-36volts d)vaf=72volts vab=6 volts vbd=72-(7*6) =30volts e) i=72/(8)=9 milli ampere f)i=72/14=5.143 milli ampere
