Combination of Resistors

Equivalent resistance of the following network is __________ Ω\Omega.

Figure

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 1

  1. The left wire shorts R1R_1, so the left end of R2R_2 is at the bottom rail (B).
  2. R2∥R3=2∥2=1 ΩR_2 \parallel R_3 = 2 \parallel 2 = 1\ \Omega; with R4R_4 in series: 3 Ω3\ \Omega.
  3. Across A–B: 3∥R5∥R6=3∥3∥3=1 Ω3 \parallel R_5 \parallel R_6 = 3 \parallel 3 \parallel 3 = 1\ \Omega.
  4. Equivalent resistance =1 Ω= 1\ \Omega.
