Find the equivalent resistance looking into terminals a and b in Figure P2.3.
Use mesh-current analysis to find the values of i1 and i2 in Figure P2.29. First, select iA clockwise around the left-hand mesh and iB clockwise around the right-hand mesh. After solving for the mesh currents, iA and iB determine the values of i1 and i2.
Assuming R0 = 2 , R1 = 2 , R2 = 5 ,R3 = 4A, and VS = 24 V in the circuit of Figure P2.55,use Kirchhoff’s voltage law and Ohm’s law to finda. ia, ib, and ic.b. The voltage across each resistance.
