Calculate 3 parallel resistors: 15kΩ, 30kΩ, 10kΩ, kΩ
This calculates the total resistance of 3 parallel resistors. It can also calculate the resistance of the last individual resistor to reach a target total resistance.
Enter any 3 values, the 4th one will be calculated:

• Connecting a 15kΩ (fifteen kiloohms), 30kΩ (thirty kiloohms) and a 10kΩ (ten kiloohms) resistors in parallel creates a 5kΩ (five kiloohms) resistance.• To a parallel combination of a 15kΩ (fifteen kiloohms) and a 30kΩ (thirty kiloohms) resistor, you need to add a 10kΩ (ten kiloohms) resistor to bring the total resistance to 5kΩ (five kiloohms).
