Zai kana Potentiometer?

Takaitaccen Potentiometer

Potentiometer (ko kuma ake kira pot ko potmeter) shine 3-terminal variable resistor da ake amfani da ita don kontrola haɗin kasa na daji mai tsarki ta tattara resistance.

Sauran Yadda Ake Amfani Da Ita

Potentiometers sun yi aiki su ne a gida sliding contact across a uniform resistance, tattaunawa voltage output based on the contact’s position.

Abubuwa Na Potentiometers

• Rotary potentiometer

• Linear potentiometer

Digital Potentiometers

Digital potentiometers sun bayar da inganci da zafiya masu yawan mechanical ones, using electronic controls to vary resistance.

Muhimmanci Na Digital Potentiometers

• Zafiya masu yawa

• Inganci masu yawa

• Mutane, abubuwa daban-daban na potentiometers za su iya zama a single chip

• Resistance drift masu haske

• Babu abubuwan da suke ci gaba

• Tolerance up to ±1%

• Very low power dissipation, up to tens of milliwatts

Matsaloli Na Digital Potentiometers

• Babu da shawarar wajen amfani da su a cikin yanayi mai karfi da yanayi mai kyau.

• The nonlinearity in the wiper resistance adds a harmonic distortion to the output signal. The total harmonic distortion, or THD, quantifies the degree to which the signal is degraded after crossing through the resistance.

Faidadantar

• Comparing the emf of a battery cell with a standard cell

• Measuring the internal resistance of a battery cell

• Measuring the voltage across a branch of a circuit
