Node driven by a Write a KCL equation for a surface current source. around the node. Branch currents are RI [ R2 (Value of current written in terms of the node voltages. (+) source may be zero). (V1-V2)/R] +(V3-V2)/R2+i=0 2. Node connected Write a KVL equation equating the 00 by a path of voltage node voltage to the sum of the source sources to the voltages. v reference node. -mod1+=0 V2 - VR + V_ = 0 3. Supernode: node Write a KVL equation relating each 1 RI R2 4 connected to node(s) node voltage to the proncipal node 217 3-w other than the voltage. Then write a KCL equation surface reference node by for a surface around the supernode. take v, as principal node voltage source(s). V3 =V2 +V (V1-V2)/R1 +[V4-(V2+V)]/R2=0 Case MESH ANALYSIS Example 1. Mesh has current Write a KCL equation relating the w source in an outside mesh current to the value of the -- branch, current source. i3 + i = 0 R1 R2 R3 2. Mesh has series Write a KVL equation equating the sum voltage source(s), of voltage drops around the mesh due to mesh current(s) to the sum of the R5 voltage source value(s). İş(R3+R5) - v = 0 (12-1))R4 + İ,R2 + v = 0 i,RI + (i ,- i2)R4 = 0 R2 R3 3. Supermesh: Meshes Write a KCL equation relating the meth share current source(s) currents to the shared current source R5 with other meshes. value(s). Then write a KVL equation around the supermesh. İ2 - İ3 + i = 0 (İ3 = i2 + i) (İ2-i1)R4+i,R2+(i, +i)(R3+R5)=0 i,RI + (i ,- 6)R4 = 0
