Voltage Divider: Me kana shi?

Zai a nan Voltage Divider?

A voltage divider shine wani matsayin aikin da ake amfani da ita a cikin sayar da takaitaccen elektronika wanda ya iya samun wata batu na shiga voltage a matsayin fadada. Ana bincike ta da amfani da biyu resistors (ko kuma passive components) da voltage source. Ana tsara resistors a matsayin series da kuma ana bayar voltage a kan hukumar da suka.

Aikin ya zama da sunan a potential divider. Voltage na shiga tana zama da jama a kan resistors (components) na aikin voltage divider. Saboda haka, tana faruwa voltage division. Idan kana neman taimakawa a kan tafarko na voltage division, zaka iya amfani da voltage divider calculator.

Circuit of Voltage Divider

Kamar yadda muna ambaci, biyu na series resistors da voltage source suka dogara wani voltage divider mai basu. Aikin ya zama da za a iya kawo da ita a wani abubuwa kamar yadda aka nufin a nan.

A cikin hakan, (A) na nufin shorthand, (B) na nufin longhand da (C) da (D) sun nuna resistors a wani abubuwa da kuma sama.

Amma duka cewa biyar na aikin sun fi yawan gaba. R1 shine resistor da ke da muhimmanci a kan input voltage source da R2 shine resistor da ke da muhimmanci a kan ground. Vout shine voltage drop across the resistor, R2.

Ya zama wani voltage divider da muna samun shi a matsayin fadada.

Equation of Voltage Divider in Unloaded Condition

A cikin hakan, an nuna wani voltage divider circuit da take da biyu electrical impedances (Z1 da Z2) ko kuma passive components da suka tsara a series. Impedances zai iya zama resistors ko kuma inductors ko kuma capacitors.

Fadada na aikin tana cikin impedance, Z2.

A cikin open-circuit output condition; ya zama ba zan iya current flow a kan output side, sannan

Tana iya tabbatar equation (1) na fadada tare da amfani da Ohm’s Law

Substitute equation (4) in (3), we get

So, the equation is proved.
The transfer function of the above equation is

This equation is also called as Divider’s

The capacitive divider circuits never allow DC input to pass. They work on AC input.

For an Inductive divider with non-interacting inductors, the equation becomes

The inductive divider divides the DC input analogous to resistor divider circuit depending on resistance and it divides AC input with regard to the inductance.

A basic low-pass RC filter circuit is shown below which comprises of a resistor and capacitor.
