Parallel resistance calculator

Calculates properties of resistors connected in parallel

Example 1: Must calculate the resistance of 1Mohm, 150kohm and 47kohm resistors connected in parallelView example
Resistor R1ohms
Resistor R2ohms
Resistor R3ohms
Resistor R4ohms
You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga

Fill at least one of the following
  • Voltage - Applied voltage through all of the resistors
  • R1...R4 - Resistors 1 to 4
