I_3-I_4-I_5=0
⇒I_3=I_4+I_5
⇒(V_1-V_2)/(1 k)=(5+V_2)/(1 k)+V_2/(2 k)
⇒2(V_1-V_2 )=(10+2V_2 )+V_2
⇒2V_1-2V_2=10V_2+2V_2
⇒2V_1=10V_2
⇒2V_1-V_2=10
I know it's bad, but I am finding this electrical element difficult.
:/ Worst case scenario if I put up what I have at least it shows I made the effort!
Hi g/neill / NewtonianAlch, I typed it all up and came up with the following according to your suggestions:
At node V_1,
I_1+I_2-I_3=0
⇒I_1+I_2=I_3
⇒(15-V_1)/(1 k)+(10-V_1)/(2 k)=(V_1-V_2)/(1 k)
⇒(30-2V_1 )+(10-V_1 )=(2V_1-2V_2)
⇒40-3V_1=2V_1-2V_2
⇒5V_1-2V_2=40
At node〖 V〗_2...
