Parallel Resistance Calculator Formula Parallel Resistance Calculator On-line Calculator can calculate the resistance value of 2 to 4 resistors in parallel. The calculation formula of parallel resistance should keep the unit consistent.
Input resistance of single resistor:
Calculation formula of resistance of parallel resistor
For example: 10Ω, 10Ω, 100Ω, 100Ω, the resistance of four resistors in parallel is R and is:
Another example: the resistance of 820Ω, 1.5kΩ two resistors in parallelRandis：
Two typical applications for shunt resistors:
1. There is no suitable resistor: when a resistor with a suitable resistance is not found, it can be obtained by connecting multiple resistors in parallel.
2, the resistance power does not meet the requirements: For example, if a 1W 25Ω resistor is needed in the circuit and there is no hand, then four 1/2W resistors with 100Ω resistance can be used in parallel to replace the power distribution evenly, four The resistance of the resistor should be as uniform as possible.
