Given the circuit diagram in Fig. P2.21, find the following voltages: V_da, V_bh, V_gc, V_di, V_fa, V_ac, V_ai, V_hf, V_fb, and V_dc.

Ans) Using KVL

We have Vfe=14+4-8=10 V

and Vbe=-12+20+Vfe=18 V

Vde=16+12-8=20 V

---------------

Vda=-8-Vbe+Vde=-8-18+20=-6 V

Vbh=Vbe+8=18+8=26 V

Vgc=12-4-14-20=-26 V

Vdi=16+12-4=24 V

Vfa=-20+12-8=-16 V

Vac=8-12=-4 V

Vai=-Vda+Vdi=6+24=30 V

Vhf=-4-14=-18 V

Vfb=-20+12=-8 v

Vdc=Vda+Vac=-6-4=-10 V
