Final answer:

When resistors are connected in parallel, the equivalent resistance can be calculated using the formula 1/Req = 1/R1 + 1/R2 + 1/R3. Substituting the given resistance values into the formula will give you the equivalent resistance.

Step-by-step explanation:

When resistors are connected in parallel, the formula to calculate the equivalent resistance is 1/Req = 1/R1 + 1/R2 + 1/R3, where Req is the equivalent resistance and R1, R2, and R3 are the individual resistances. In this case, the values are:

  • R1 = 25.21 ohms
  • R2 = 16.83 ohms
  • R3 = 19.87 ohms

Substituting these values into the formula gives:

1/Req = 1/25.21 + 1/16.83 + 1/19.87

Solving this equation will give you the value for Req, which is the equivalent resistance.
