Jinsi ya kukokotoa Voltage Divider
Voltage Divider ni nini?
Calculates output voltage from a resistor network dividing input voltage. Used for ADC inputs, sensor interfaces, and voltage scaling.
Fomula
Formula: Vout = Vin × (R2 ÷ (R1 + R2))
- R2
- R2 value — Variable used in the calculation
- R1
- R1 value — Variable used in the calculation
Mwongozo wa Hatua kwa Hatua
- 1Two resistors in series across supply voltage
- 2Output taken between resistors
- 3Formula: Vout = Vin × (R2 ÷ (R1 + R2))
- 4Select resistors to achieve desired output voltage
Mifano Iliyotatuliwa
Ingizo
V1=12V, R1=1k, R2=1k
Matokeo
Vout=6V
Makosa ya Kawaida ya Kuepuka
- ✕Not buffering voltage divider with low-impedance load
- ✕Using very small resistor values (excessive power)
Maswali yanayoulizwa mara kwa mara
What affects voltage divider accuracy?
Load impedance (must be much higher than resistor values), temperature stability, resistor tolerance.
How do I buffer a voltage divider?
Use op-amp buffer to isolate divider from load; prevents voltage drop under load.
