Answer 1

The Correct option is 1

Concept:

Suppose R₁= 2 ohm

R₂= 6 ohm

R₃ =12 ohm

V = I * R

V = Voltage source

I = Current source

R = Value of resistance

R₂ and R₃ are in parallel = _{\({\mathbf{\frac{R_{2}\times R_{3}}{R_{2}+R_{3}}}}\)} = R₂₃

R equivalent = R₂₃+R₁

I = \(\frac{V}{R_{Equivalent}}\)

Calculation:

V = 12volts

R₂₃ = \(\frac{6\times 12}{18}=4\Omega \)

\(R_{Equivalent}\)= 4+2= 6 ohm

I = \(\frac{V}{R_{Equivalent}}\)= \(\frac{12}{6}=2A\)
