Thank you gneill, i'll have to look at it and perhaps get a physics tutor.

Homework Statement 1 (a) using complex notation, find an expression for the output voltage, v0 1 (b) using complex notation, find an expression for the input current, ig, and hence determine the phase angle of ig relative to vg Homework Equations The Attempt at a Solution...

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!

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, 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=10 Solving the two...

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...

Hi gneill / NewtonianAlch - thank you kindly for your welcome and for your suggestions, I will review this PM.

Homework Statement 1. Using Kirchhoff’s Laws, find all the currents flowing in the circuit. 2. Hence, determine the voltage across each resistor and show that all loops comply with KVL Homework Equations KVL and KCL The Attempt at a Solution Please see the pictures...
