Electrical Electronics کا حساب کیسے لگائیں
Electrical Electronics کیا ہے؟
Electrical and electronics calculators cover resistor selection, circuit analysis, power calculations, and component sizing. They are used by hobbyists, technicians, and engineers designing circuits.

- 1LED resistor: R = (Vsupply − Vforward) / I_forward
- 2Voltage divider: Vout = Vin × R2 / (R1 + R2)
- 3Power factor: PF = real power (W) / apparent power (VA)

5V supply · LED Vf = 2.0V · If = 20mA
نتیجہ
R = (5 − 2) / 0.02 = 150 Ω (use 150 Ω standard value)
Always round up to the nearest standard resistor value
