Resistors are in parallel if their terminals are connected to the same two nodes. The equivalent overall parallel resistance is smaller than the smallest parallel resistor.

Parallel resistors simulation model.

  • Compute the current in R1 and R2. Add them together.
  • Compute an equivalent parallel resistor for the two resistors.
  • Find the current flowing in the equivalent resistor.
  • Compare the sum of i1 + i2 to the current in the equivalent resistor.
  • Click on DC to run the simulation. Does the simulator match your calculations?
