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)

a. Current I flows through x₁ , x₂ and x₃

b. x is larger than x₁ , x₂ and x₃

c. x is smaller than x₁ , x₂ and x₃

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

e. x = x₁ + x₂ + x3
f. $\mathrm{x}=\frac{1}{{\displaystyle \frac{1}{{\mathrm{x}}_1}}+{\displaystyle \frac{1}{{\mathrm{x}}_2}}+{\displaystyle \frac{1}{{\mathrm{x}}_3}}}$
