T6A03
What electrical parameter is controlled by a potentiometer?
- A.Inductance
- B.Resistance (correct answer)
- C.Capacitance
- D.Field strength
WhyA potentiometer controls resistance. A potentiometer is fundamentally a variable resistor, so the electrical parameter it adjusts is resistance, answer B. Inductance (A), capacitance (C), and field strength (D) are all different physical quantities that a resistive component like a potentiometer doesn't control.
