# Rangkaian Voltage Divider
|
|
|
|
Rangkaian **voltage divider** membagi tegangan input menjadi tegangan yang lebih kecil
|
|
menggunakan dua resistor.
|
|
|
|
## Rumus
|
|
|
|
```
|
|
Vout = Vin * (R2 / (R1 + R2))
|
|
```
|
|
|
|
Jika R1 = R2 = 1kΩ dan Vin = 5V:
|
|
```
|
|
Vout = 5 * (1000 / (1000 + 1000)) = 2.5V
|
|
```
|
|
|
|
## Contoh Rangkaian
|
|
|
|
Berikut rangkaian voltage divider sederhana:
|
|
|
|
```circuit
|
|
<cir f="1" ts="0.000005" ic="10.20027730826997" cb="50" pb="50" vr="5" mts="5e-11">
|
|
<v x="80 200 80 112" f="0" wf="0" maxv="5"/>
|
|
<r x="80 112 176 112" f="0" r="1000"/>
|
|
<r x="176 112 176 200" f="0" r="1000"/>
|
|
<w x="176 200 80 200" f="0"/>
|
|
<ln x="176 112 208 32" f="0" te="Vout"/>
|
|
</cir>
|
|
```
|
|
|
|
Perhatikan tegangan di **Vout** adalah ~2.5V.
|
|
|
|
---EXERCISE---
