Question

Calculate what is asked

R1 R3 R5 2k 4k 3k. R43 > 5k 12V * R23 1k + ne voltages Va, VÝ, Vc, Va, I4 and current in each resistor

Answer 1

Giren circuit raga za 12v т K fa 2K to 4k Lc 3k Ry? Ska I , Tik +1 1 Risk f4 -1 gy + -7 epik sitt it 8 By using nodal Analysis Consider modes a, b, c, d fo as shown and their potentials as va, Vbi Ve Vd and ground at the respective nodes. By observation Ve = 12 volts. -8 volts. ka at node "b" Y + X=Y - > v[*++ ++3+ [1 = V(2]+v[-4)=6 → Equation
