Question
For the circuit find the Voltage V2 using any of the methods seen on class. You might need to use auxiliary equations, such as V2-V1=18V to obtain the final values. It is recommended that you label the currents in all components, and all the voltages during your analysis to facilitate the process.
b) For the circuit above find the voltage V1
c) For the circuit above finde the current across Vs2
d) Find the current across R1
For the circuit find the Voltage V2 using any of the methods seen on class. You might need to use auxiliary equations, such as V2-V1=18V to obtain the final values. It is recommended that you label the currents in all components and all the voltages during your analysis to facilitate the process.Explanation / Answer
Using nodal analysis
V3=4 V
at node V1: (4-V1)/2=(V1/4)+i .....(1) (assuming i is the current flowing through Vs2 source from -ve to +ve)
at node V2: 2+i=(V2/8).....(2) (assuming i is the current flowing through Vs2 source from -ve to +ve)
V2-V1=18........(3)
solving these 3 equations we get
b) V1=2V
V2=20 V
puting V2 in equation (2) we get i=0.5A
c) So current accross Vs2 is 0.5 A
d) Current accross R1 is iR1=(4-2)/2=1A
