Current divider rule

I₁ = I_total × (R_total / R₁) where R_total = (R₁ × R₂) / (R₁ + R₂)

For two-branch dividers the current through one resistor equals total current multiplied by the ratio of the opposite resistance over the sum.

How to use

  1. Enter the total supply current.
  2. Provide the resistances of each branch (add a third branch if required).
  3. Review individual branch currents and verify they sum back to the source.

Example

Input: Itotal = 2.5 A, R1 = 220 Ω, R2 = 330 Ω

Output: I₁ ≈ 1.5 A, I₂ ≈ 1.0 A

Deep dive & study plan

The Current Divider Calculator is a go-to tool whenever you need to splits current through resistors in a parallel branch.. It focuses on current divider, parallel circuit, resistance, which means searchers often arrive with intent-heavy queries like “how to current divider calculator quickly” or “current divider calculator formula explained.” Use this calculator to capture those intents and keep learners on the page long enough to send positive engagement signals.

Under the hood, the calculator leans on for two-branch dividers the current through one resistor equals total current multiplied by the ratio of the opposite resistance over the sum.—that’s why we surface the full expression (“I₁ = I_total × (R_total / R₁) where R_total = (R₁ × R₂) / (R₁ + R₂)”) directly above the interactive widget. When you embed that formula inside H2s or supporting paragraphs, you help both humans and crawlers understand what entity the page represents.

Execution matters as much as the math. Follow the built-in procedure: Step 1: Enter the total supply current. Step 2: Provide the resistances of each branch (add a third branch if required). Step 3: Review individual branch currents and verify they sum back to the source.. Each numbered instruction is short enough to scan on mobile but descriptive enough to satisfy Google’s Helpful Content guidelines. Encourage students to jot down units, double-check signs, and compare answers with the Example card to build confidence.

The Example section itself is packed with semantic clues: “Itotal = 2.5 A, R1 = 220 Ω, R2 = 330 Ω” leading to “I₁ ≈ 1.5 A, I₂ ≈ 1.0 A.” Pepper similar narratives throughout your copy (and internal links from related guides) so canonical search intents are answered without pogo-sticking back to Google.

Quick retention checklist

  • Speak the formula aloud (or annotate it) so the relationships stick.
  • Write each step in your own words and compare with the numbered list above.
  • Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
  • Link out to at least two related calculators to keep readers exploring your topical hub.

FAQ & notes

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.

What formula does the Current Divider Calculator use?

For two-branch dividers the current through one resistor equals total current multiplied by the ratio of the opposite resistance over the sum.

How do I use the Current Divider Calculator?

Enter the total supply current. Provide the resistances of each branch (add a third branch if required). Review individual branch currents and verify they sum back to the source.
