With 15 ohm and 20 ohm conductors connected in parallel, calculate the total connection resistance.
| January 15, 2021 | education
When the conductors are connected in parallel, their total resistance is:
1 / R = (1 / R1) + (1 / R2)
Let’s bring to a common denominator:
1 / R = (R1 + R2) / (R1 * R2)
Let us express the total resistance:
R = (R1 * R2) / * (R1 + R2)
Substitute the numerical values and calculate:
R = (R1 * R2) / * (R1 + R2) = (15 * 20) / (15 + 20) = 8.57 Ohm
Answer: When connected in parallel, the total resistance is 8.57 ohms.
