Answer 1

we have the following circcuit + V2 - och 122 mette vi love lov loves uz sava The circuit can be ue drawn as I uz y xuu bu izce sch lov (A) V3 VŹlor vi flour 6 V 152 § The lou resistore is directly in parallel with the sowice 80, V3: 16V We can determine vu uning voltage dividen. The voltage across the series combination of the sch and the 15ch mesistou is lov as it is in parallel with the sounce, so we have using voltage divider Vyr 15 x 16 e 18 x to 12V 5 + 15 A V4 - 12V To determine V2 and vi, we will again use voltage divider rule. V2 is the negative of the voltage across the parallel combination of the our and the 12c2 resistor, as it will be same with them being in parallel. i can then be

devived simply using the voltage divider rule. The equivalent resistance (say Real of the pare allel combination is ur 724 18 Reae 6 X 12 6+12 can uedraw we the as: cire cuit Req = 4 ctts Ourš uz www 6V 2 vi Žlour ule Therefore, using voltage dividere V22 - X162- to- 20s 1 V22-32 V similarly, VE 16X163 16 x 460 64 4 + 16 20 5 V2 2 12.8V
