learn.whatIsHeading

Calculates current distribution across parallel resistors. Shows how current splits in parallel paths.

Formel

Formula: I1 = Itotal × (R2 ÷ (R1 + R2))
I1
Itotal × (R2 ÷ (R1 + R2)) — Itotal × (R2 ÷ (R1 + R2))
R2
R2 value — Variable used in the calculation
R1
R1 value — Variable used in the calculation

Trinn-for-trinn guide

  1. 1Parallel resistors with same voltage across them
  2. 2Formula: I1 = Itotal × (R2 ÷ (R1 + R2))
  3. 3Current inverse to resistance
  4. 4Lower resistance draws more current

Løste eksempler

Vanlige feil å unngå

  • Confusing current divider with voltage divider behavior
  • Not accounting for wire resistance in parallel paths

Ofte stilte spørsmål

How does parallel resistance differ from series?

Parallel: currents add, voltage same, total R less than smallest; series: opposite.

Why use current dividers?

Share current load, calibrate sensors, and impedance matching.
