Question

Three resistances x₁ , x₂ and x₃ are connected in a circuit in different ways. x is the effective resistance. The properties observed for these different ways of connecting x₁ , x₂ and x₃ are given below. Write the way in which they are connected in each case. (I-current, V potential difference, x-effective resistance)

1. Current I flows through x₁, x₂ and x₃

2. x is larger than x₁ , x₂and x₃

3. x is smaller than x₁, x₂ and x₃

4. The potential difference across x₁, x₂ and x₃ is the same

5.  x = x₁ + x₂ + x3
6. x = \(\frac{1}{\frac{1}{x_1}+\frac{1}{x_2}+\frac{1}{x_3}}\)

Answer 1

1. In this case, x₁,x₂ and x₃ are connected in series.

2.  In this case, x₁ , x₂ and x₃ are connected in series.

3.  In this case, x₁ , x₂ and x₃ are connected in parallel.

4. In this case, x₁ , x₂ and x₃ are connected in parallel.

5. In this case, x₁ , x₂ and x₃ are connected in series.

6. In this case, x₁ , x₂ and x₃ are connected in parallel.
