Question

hey, can you solve no. 4 ?

Answer 1

Equivalent Resistance = sum of all resistance in the circuit

In here we have both series and parallel combinations

series = 2∩

parallel  = Rₓ = 1/R₁ + 1/R₂ + 1/R₃ = 1/3 + 1/1+2) + 1/3 = 3/3 = 1∩

Equivalent Resistance = 2 + 1 = 3∩

Current =voltage source/ Equivalent resistance

current = 12v/3∩ = 4A

Voltage in 1∩ = 1/3 x 12 = 4v

Current in 1∩ = 4/1 = 4A

I tried my best. Do you have answers?
