Answer 1

Answer:

i2 = 3/5 A

i3 = 2/5 A

Explanation:

Since you didn't mention what to find in the Q, I'll find i2 and i3

The resistors R2 and R3 are connected in parallel which means the voltage drop at R2 and R3 will be the same.

V2 = V3

i2R2 = i3R3. ---(1) (from ohms law: V = IR)

But from Kirchhoff's current rule we get: (consider any one of the junctions)

i1 = i2 + i3

1 = i2 + i3

i3 = 1 - i2 -----(2)

substitute in eq (1)

i2R2 = (1 - i2)R3

i2(10) = (1 - i2)(15)

i2(2) = 3 - 3i2

5i2 = 3

i2 = 3/5 A

i3 = 2/5 A
