Jinsi ya kukokotoa Electrical Electronics
Electrical Electronics ni nini?
Electrical and electronics calculators cover resistor selection, circuit analysis, power calculations, and component sizing. They are used by hobbyists, technicians, and engineers designing circuits.
Mwongozo wa Hatua kwa Hatua
- 1LED resistor: R = (Vsupply − Vforward) / I_forward
- 2Voltage divider: Vout = Vin × R2 / (R1 + R2)
- 3Power factor: PF = real power (W) / apparent power (VA)
Mifano Iliyotatuliwa
Ingizo
5V supply · LED Vf = 2.0V · If = 20mA
Matokeo
R = (5 − 2) / 0.02 = 150 Ω (use 150 Ω standard value)
Always round up to the nearest standard resistor value
