Question

Two resistances R1 = (100 ± 3) Ω, R2 = (150 ± 2) Ω, are connected in series. What is their equivalent resistance?

Answer 1

Answer:

(250 ± 5) Ω

Explanation:

Given :

R₁ = (100 ± 3) Ω

R₂ = (150 ± 2) Ω

To find :

The equivalent resistance in series

Formula :

If R₁ and R₂ are connected in series, R eq = R₁ + R₂

Error should always be added

Solution :

R eq = 100 + 150 = 250

Error = 2 + 3 = 5

Hence, the equivalent resistance = (250 ± 5) Ω

Hope it helps!
