Kuinka laskea Electrical Electronics
Mikä on Electrical Electronics?
Electrical and electronics calculators cover resistor selection, circuit analysis, power calculations, and component sizing. They are used by hobbyists, technicians, and engineers designing circuits.
Vaiheittainen opas
- 1LED resistor: R = (Vsupply − Vforward) / I_forward
- 2Voltage divider: Vout = Vin × R2 / (R1 + R2)
- 3Power factor: PF = real power (W) / apparent power (VA)
Ratkaistut esimerkit
Syöte
5V supply · LED Vf = 2.0V · If = 20mA

R = (5 − 2) / 0.02 = 150 Ω (use 150 Ω standard value)
Always round up to the nearest standard resistor value
