Calculating the Restor Value
Ini adalah sisa dari data (R) cae be kalkulated using ohm 's Law: R = (V ax1; FLT: 0: 3; Aver3; S 1; FLT: 1: 1 Of3s; -V MIS1; FLT: 2 WLT: 3F 113; S01; FLT: 3: 333I perdetik, I perdetik.
Pemeriksaan singkat, with V Aver1; FLT: 0: 33; S 1; FLT: 1: 1 After3; = 5V, V = 2V, FLT: 2: 23; F Aver1; FL1; FLT: 3; FLT: 3: 3 FLT: 3 MIS33; = 2V, and I = 0.02A (20ma):
R = (5V - 2V) / 0.02A = 3V / 0.02A = 1501f
Choosing the Restor
Resisstors come in standard valuees.
- Deterae the LED 's forward voltale (V 11r; FLT: 0 123; F 1f; FLT: 1 123; 123;).
- Deciddy on the decred recreat (Usally 20mA).
- Use formula R = (V = 11r; FLT: 0: 33; SYL3; S 1; FLT: 1: 1; Aver3; - V 1; FLT: 2: 23; F MIL1; FL1; FLT: 3; 3; 33;) / I.
- Selet bahwa e closest standard resistor value.
