Tính điện trở qua phương pháp vẽ lại mạch điện cực hay | Vật Lí lớp 9

Sơ đồ mạch: R1 // [R2 nt (R3 // R4)]

\(R_{34}=\dfrac{R_3\cdot R_4}{R_3+R_4}=\dfrac{6\cdot6}{6+6}=3\left(\text{Ω}\right)\)

\(R_{234}=R_2+R_{34}=9+3=12\left(\text{Ω}\right)\)

\(R_{tđ}=\dfrac{R_1\cdot R_{234}}{R_1+R_{234}}=\dfrac{12\cdot12}{12+12}=6\left(\text{Ω}\right)\)

theo mạch điện như hình vẽ

\(=>\left(R1ntR3\right)//R2]ntR4\)

do đó \(=>Rtd=R4+\dfrac{\left(R1+R3\right)R2}{R1+R3+R2}\)

\(=6+\dfrac{\left(12+6\right)9}{12+6+9}=12\left(om\right)\)

Sơ đồ mạch: R1 // [R3 nt (R2 // R4)]

\(R_{24}=\dfrac{R_2\cdot R_4}{R_2+R_4}=\dfrac{5\cdot10}{5+10}=\dfrac{10}{3}\left(\text{Ω}\right)\)

\(R_{234}=R_3+R_{24}=5+\dfrac{10}{3}=\dfrac{25}{3}\left(\text{Ω}\right)\)

\(R_{AB}=\dfrac{R_1\cdot R_{234}}{R_1+R_{234}}=\dfrac{10\cdot\dfrac{25}{3}}{10+\dfrac{25}{3}}=\dfrac{50}{11}\left(\text{Ω}\right)\)
