Question

Two resistors $R_1(24\pm 0.5)\Omega$ and $R_2(8\pm 0.3)\Omega$ are joined in series. The equivalent resistance is

• A. $32\pm 0.33\Omega$
• B. $32\pm 0.8\Omega$
• C. $32\pm 0.2\Omega$
• D. $32\pm 0.5\Omega$

Answer 1

Answer: (B)

$32\pm 0.8\Omega$

R₁ = 24 ± 0.5

R₂ = 8 ± 0.3

In series R₁ + R₂ = 32 ± 0.8
