Answer:

If resistors are connected in parallel circuit then equivalent resistance R

= 1/R = 1/R₁ + 1/R₂ + 1/R₃

Here R = 3 , R₁ = 10 , R₂ = 30

∴1/3 = 1/10 + 1/30 + 1/R₃

= 1/3 = 4/30 + 1/R₃

= 1/3 - 4/30 = 1/R₃

= 10 - 4 /30 = 1/R₃

= 6 / 30 = 1/R₃

= 1/R₃ = 1/5

∴ R₃ = 5Ω

∴ Third Resistor = 5Ω
