Current Divider Calculator Guide

Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.

Before you start

Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.

  • current divider
  • parallel circuit
  • resistance

Detailed procedure

  1. Step 1

    Enter the total supply current.

  2. Step 2

    Provide the resistances of each branch (add a third branch if required).

  3. Step 3

    Review individual branch currents and verify they sum back to the source.

Teaching & troubleshooting tips

Can I add more than two branches?

Yes—toggle the third branch option to include a third resistor. For more branches duplicate the pattern in your own spreadsheet.

Is power dissipation shown?

Each branch lists wattage so you can confirm resistor ratings before soldering.
