Jak vypočítat Current Divider
Co je Current Divider?
Calculates current distribution across parallel resistors. Shows how current splits in parallel paths.
Vzorec
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
Průvodce krok za krokem
- 1Parallel resistors with same voltage across them
- 2Formula: I1 = Itotal × (R2 ÷ (R1 + R2))
- 3Current inverse to resistance
- 4Lower resistance draws more current
Worked Examples
Vstup
I=10A, R1=2ohm, R2=2ohm
Výsledek
I1=5A, I2=5A
Common Mistakes to Avoid
- ✕Confusing current divider with voltage divider behavior
- ✕Not accounting for wire resistance in parallel paths
Frequently Asked Questions
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.
