Answers :
Part a)
Total equivalent resistance = 11.67 Ω
(answer and working is provided in the attached file)
Part b)
Vт = Iт × Rт
28.8 = Iт × 11.67
Iт = 28.8/11.67
Iт = 2.47 A
Current in 12Ω :
12+6 = 18 Ω
= 12/18 × 2.47
= 1.65 A
Current in 6Ω :
= 6/18 × 2.47
= 0.82 A
Current in 5Ω :
= 2.47 A (as the current in a series circuit will be equal to the total current)
Current in 4Ω :
4+8 = 12 Ω
= 4/12 × 2.47
= 0.82 A
Current in 8Ω :
= 8/12 × 2.47
= 1.65 A
