Multiple resistors in parallel can be combined into a single equivalent resistor.

Parallel resistors simulation model.

  • Compute the currents in the individual resistors. i1 = 3V/R1, i2 = 3V/R2, etc.
  • Compute an equivalent parallel resistor for the four resistors using the parallel resistor formula from this video.
  • Find the current flowing in the equivalent resistor. i_total = 3V/Requiv
  • Compare the sum of individual currents to the current in the equivalent resistor.
  • Click on DC to run the simulation. Does the simulator match your calculations?
