the equivalent resistance between a and b is​

Answer 1

Answer:

$\color{blue}\underline{we \: start \: from \: the \: last} \\ \color{red}1Ω \: and \: 1Ω \: in \: series : \\ R_s = 1 + 1 = 2Ω \\ \color{red}R_s \: and \: 2Ω \: in \: parallel : \\ R_p = \frac{R_s \times 2}{R_s + 2} = \frac{4}{4} = 1Ω \\ \color{red}R_p \: and \: 1Ω \: in \: series : \\ R_{s1} = R_p + 1 = 2Ω \\ \color{red}R_{s1} \: and \: 2Ω \: in \: parallel : \\ R_{eq} = \frac{R_{s1} \times 2}{R_{s1} + 2} = \frac{4}{4} \\ \\ \boxed{R_eq = 1Ω} \\ \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
