If three resistors are all connected in parallel, find the total resistance in the circuit. R1 = 41Ω, R2 = 20Ω and R3 = 38Ω. Answer to 1 decimal place and only put in the numerical value. Do not write the unit in your answer.

Question

BlackTom AI · Accepted Answer

When resistors are in parallel, the reciprocals of the resistances add: 1/Rt = 1/R1 + 1/R2 + 1/R3.
Substitute the given values: 1/Rt = 1/41 + 1/20 + 1/38.
Compute each term: 1/41 ≈ 0.02439, 1/20 = 0.05, 1/38 ≈ 0.02632.
Add them together: 0.02439 + 0.05 + 0.02632 ≈ 0.10071.
Take the reciprocal to find the total resistance: Rt ≈ 1 / 0.10071 ≈ 9.93 Ω.
Since the instruction asks for the answer to 1 decimal place, round 9.93 to 9.9.
Thus, the total resistance of the parallel combination is approximately 9.9 (to 1 decimal place).
