Basic Concept of Voltale Dividers
Sebuah voltape divider kontra of twot connected ion serieos across a voltape source volput o.
Calculating Restor Values
Ini fundamental untuk dua for voltape divider is:
FL1; FLT: 0 = 0 = 33; V = 1; FLT: 1: 1; 13; O3; Of1; FLT: 2: 33334; = V; FL1T; L33T; L32RD; 3332R\ = 32RE; 332TH3; 32THN; 32R2THN; 322RN; 32THN; 32222RN; 32222RN;
Dimana:
- V = 111; ASA1; FLT: 0 = 33; in = Input voltale
- V 1991; ASA1; FLT: 0 AF3; OUT OUT 1; ASA1; FLT: 1 ASA3; = Desired output voltale
- R 11; ASA1; FLT: 0 AF3; 1; 1; 1; FLT: 1: 1 Aver3; AND R; FLT: 2: 2 GUNIS; 2; 2 FLT: 3 MIS33; = resistor data
To frid R 1f; 1f FLT: 0 Abo3; 21. FLT: 1 After3;, returrange the formula:
FL1; FLT: 0 = 33; R = 1; FLT: 1: 1; 13; 2; FLT: 2: 2; 3; 3; 1; 1; 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 =

Addonional Tips
Use standard resistor values close to the kalkulated resistance. Contider the impact of resistor lentiance on te output voltage. For precesse proporces, select resistors with low lenlianpe valueos.
