Electrical Electronics Nasıl Hesaplanır?
learn.whatIsHeading
Electrical and electronics calculators cover resistor selection, circuit analysis, power calculations, and component sizing. They are used by hobbyists, technicians, and engineers designing circuits.
Adım Adım Kılavuz
- 1LED resistor: R = (Vsupply − Vforward) / I_forward
- 2Voltage divider: Vout = Vin × R2 / (R1 + R2)
- 3Power factor: PF = real power (W) / apparent power (VA)
Çözümlü Örnekler
Giriş
5V supply · LED Vf = 2.0V · If = 20mA
Sonuç
R = (5 − 2) / 0.02 = 150 Ω (use 150 Ω standard value)
Always round up to the nearest standard resistor value
