Answer 1

Answer #1

Part A : Find the current through the 30 resistor.

using a KVL in loop 1, we have

- I₁ (30 ) = 0

(8 V) = I₁ (30 )

I₁ = [(8 V) / (30 )]

I₁ = 0.266 A

Part B : Find the current through the 18.4 resistor.

using a KVL in loop 2, we have

- I₂ R - (5 V) = 0

[(8 V) - (5 V)] = I₂ (18.4 )

(3 V) = I₂ (18.4 )

I₂ = [(3 V) / (18.4 )

I₂ = 0.163 A

Part C : Find the current through the 8 V battery.

we know that, I_total = I₁ + I₂

I_total = [(0.266 A) + (0.163 A)]

I_total = 0.429 A
