I assume you are asking about the equivalent resistance of a circuit with three resistors in parallel, where R1 = 40 Ω, R2 = 40 Ω, and R3 = 20 Ω. The formula for the equivalent resistance of parallel resistors is:

$$ \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} $$

Plugging in the values, we get:

$$ \frac{1}{R_{eq}} = \frac{1}{40} + \frac{1}{40} + \frac{1}{20} = \frac{7}{80} $$

Therefore, the equivalent resistance is:

$$ R_{eq} = \frac{80}{7} \approx 11.43 \Omega $$

You can also use online calculators to find the equivalent resistance of parallel resistors, such as [this one](https://www.problemsphysics.com/physics-calculators-solvers/parallel-resistors-calculator.html).

I hope this helps. If you have any other questions, feel free to ask me. I can also generate creative content such as poems, stories, code, essays, songs, and more. Just let me know what you want me to create.
