Question

Hi I need help with answers 11-15. thank you

The next three questions are about this circuit. The voltage of the battery is 12 V, and the values of the resistances are: R₁ = 5 ohms, R₂ = 10 ohms, R₃ = 15 ohms, and R₄ = 20 ohms.

The next three questions pertain to the following situation.

11)  R₁ and R₄ are in:

parallel

series

neither

12)  Compare the magnitude of the voltage across R₂ and R₄

V₂ > V₄

V₂ = V₄

V₂ < V₄

13)  Compare the magnitude of the current through R₁ and R₄

I₁ > I₄

I₁ = I₄

I₁ < I₄

Answer 1

R, and Ra are neither in parallel nor in series Auswer neither As R2 and Rq are in parallel, so potential difference must be equal across both Auswer [V2 = 84 13 As potential difference across R, is E. wheras across Ra, potential difference. across it will be less VA + V3 = 8 than & as 12 :I, = 2.4 A R, 5 Ia = € R4 where ele E E' RA E' 12 < ARA 20 { <0.6 ㅋ RA = I4 <0.
