Solved Step by Step with Explanation- Circuit with 20V Source

We have to find the current Ix with help of circuit reduction and Current and Voltage division rules.

R1=10 Ω|

And 10 Ωand10 Ω which is connected between nodes A and B are parallel, the equivalent will be,

And the resistors R1 (Obtained series combination of 7 Ωand3 Ω) and 10 Ω parallel

Hence, Combination will be,

2.5×102.5+10=2 Ω

The equivalent circuit will be,

VA=20×2/5

VA=8 V

VB=VA×R4/R2+R4 (see in the circuit reductions)

VB=8×5(5+5)

Ix=VB/10

Ix=4/10
