(a). The Resistors Connected in Series are,
R₁ & R₂ and R₅ and R₁
(b). The Resistors Connected in the Parallel combination are,
R₂ and R₃.
(c). Now, Every Resistors have the Resistance equal to 2 Ω.
Therefore, we need to find the equivalent Resistance.
R₂ and R₃ area in parallel, and R' be the Resultant of these two resistors.
∴ 1/R' = 1/2 + 1/2
∴ 1/R' = 1
∴ R' = 1 Ω
Now, Rest of the all resistors are in series.
∴ Equivalent Resistance = R' + R₁ + R₄ + R₅
= 1 + 2 + 2 + 2
= 7 Ω
Using the Ohm's law,
V = IR
V = 5 V
Therefore,
I = V/R
∴ I = 5/7
∴ I = 0 .7 A
