What will be the most suitable combination of three resistors A=2 Ω, B=4 Ω, C=6 Ω, so that ((22)/3)Ω is equivalent resistance of combination?

Asked in JEE Main 24th June 2nd Shift 2022 · Series and parallel combinations

• (1) Parallel combination of A and C connected in series with B.
• (2) Parallel combination of A and B connected in series with C.
• (3) Series combination of A and C connected in parallel with B.
• (4) Series combination of B and C connected in parallel with A.

Step-by-step solution

Why the other options are wrong

• (1) Gives 2∥6+4=1.5+4=5.5 Ω, not (22)/3 Ω.
• (3) Gives (2+6)∥4=8/3 Ω.
• (4) Gives (4+6)∥2=5/3 Ω.
