Electrical Electronics ની ગણતરી કેવી રીતે કરવી
Electrical Electronics શું છે?
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)
Worked Examples
ઇનપુટ
5V supply · LED Vf = 2.0V · If = 20mA
પરિણામ
R = (5 − 2) / 0.02 = 150 Ω (use 150 Ω standard value)
Always round up to the nearest standard resistor value
