10kΩ and 10kΩ in parallel = 5kΩ

Worked answer for a 10kΩ and a 10kΩ resistor wired in parallel.

Equivalent resistance 5kΩ 10kΩ and 10kΩ in parallel
Resistor 1 (R1)10kΩ
Resistor 2 (R2)10kΩ
Connection modeparallel
FormulaR = 1 / (1/R1 + 1/R2)
Equivalent resistance5kΩ

Resistors in parallel always give an equivalent resistance smaller than the smallest resistor in the group.

Different values? Add as many resistors as you like and switch between series and parallel in the interactive tool:

Disclaimer: This is the ideal equivalent resistance. Real resistors have a tolerance (typically ±1% to ±5%), so the measured value will vary slightly. Confirm against your components' tolerance band when precision matters.
