This transformation can be easily done by using
equations (i), (ii) and (iii) given above. Multiplying (i) and (ii), (ii) and
(iii), (iii) and (i) and adding them together and then simplifying them, we get
equations (i), (ii) and (iii) given above. Multiplying (i) and (ii), (ii) and
(iii), (iii) and (i) and adding them together and then simplifying them, we get
From the figure above, total circuit resistance
= 20.6 + 6 + 5
= 31.6Ω
Hence I = 30/31.6
=
0.95A
0.95A
