cho mình hỏi sao câu 1 khoanh a vậy

a, \(I_1=I_3=2I_2\)

\(I_2=\dfrac{7,8}{12}=0,65\left(A\right)\) \(\Rightarrow I_3=I_1=1,3\left(A\right)\)

\(\Rightarrow U_3=7,8-U_1=7,8-1,3.4=2,6\left(V\right)\)

\(\Rightarrow R_3=\dfrac{2,6}{1,3}=2\left(\Omega\right)\)

b, k đóng ta có mạch (R1//R2)nt(R3//R4)

\(\Rightarrow R_{tđ}=\dfrac{4.6}{10}+\dfrac{2.6}{8}=3,9\left(\Omega\right)\)

\(\Rightarrow I_k=\dfrac{7,8}{3,9}=2\left(A\right)\)

\(\Rightarrow U_{12}=\dfrac{4.6}{10}=2,4\left(V\right)\)

\(\Rightarrow U_{34}=2.1,5=3\left(V\right)\)

\(\Rightarrow I_1=\dfrac{2,4}{4}=0,6\left(A\right);I_2=\dfrac{2,4}{6}=0,4\left(A\right)\)

\(\Rightarrow I_3=\dfrac{3}{2}=1,5\left(A\right);I_4=\dfrac{3}{6}=0,5\left(A\right)\)

\(A=2^{2022}-2^{2020}+...+2^2-1\)

\(\Rightarrow4A=2^{2024}-2^{2022}+...+2^4-2^2\)

\(\Rightarrow A+4A=2^{2024}-1\)

\(\Rightarrow5A=2^{2024}-1\)

Đồng thời: \(B=2^{2023}\Rightarrow2B=2^{2024}\)

Mà \(2^{2024}>2^{2024}-1\)

\(\Rightarrow5A< 2B\)

a, khi K mở \(=>[\left(R1ntR2\right)//\left(R3ntR4\right)]ntR5\)

ampe kế chỉ 0,5A\(=>I\left(A\right)=Im=I5=I1234=0,5A\)

\(=>U5=I5.R5=0,5.15=7,5V\)

\(=>U1234=Um-U5=12-7,5=4,5V\)

\(=>R1234=\dfrac{U1234}{I1234}=\dfrac{\left(R1+R2\right)\left(R3+R4\right)}{R1+R2+R3+R4}\)

\(< =>\dfrac{4,5}{0,5}=\dfrac{\left(12+R2\right)\left(4+8\right)}{24+R2}=9=>R2=24\left(om\right)\)

b, ta có R2=24 

\(\Rightarrow\dfrac{R_1}{R_3}=\dfrac{R_2}{R_4}\) mạch cầu cb

cđ dđ qua K bằng 0

\(R_{tđ}=\dfrac{R_{12}.R_{34}}{R_{12}+R_{34}}+R_5+R_a=25\left(\Omega\right)\)

\(\Rightarrow I_a=\dfrac{12}{25}=0,48\left(A\right)\)
