Calculate 2 parallel resistors: 15kΩ, 30kΩ, kΩ
This calculates the total resistance of 2 parallel resistors.
It can also calculate the resistance of the last individual resistor to reach a target total resistance.
Enter any 2 values, the 3rd one will be calculated:

Parallel resistors rule says:
•Connecting a 15kΩ (fifteen kiloohms) resistor and a 30kΩ (thirty kiloohms) resistor in parallel creates a 10kΩ (ten kiloohms) resistance.
•A 15kΩ (fifteen kiloohms) resistor resistance can be reduced to 10kΩ (ten kiloohms) by connecting a 30kΩ (thirty kiloohms) resistor in parallel.
