learn.whatIsHeading

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

공식

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

단계별 가이드

  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

풀어진 예시

입력
I=10A, R1=2ohm, R2=2ohm
결과
I1=5A, I2=5A

피해야 할 일반적인 실수

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

자주 묻는 질문

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.
