Which component has 3 leads and two leads connected to maximum resistance points with a third lead wrapped around the resistor?

• A. Has 3 leads , 2 are connected to max resistance points and the third is wrapped around the resistor
• B. Has 2 leads and a slider
• C. A coil that stores energy
• D. A fixed resistor with color bands

Answer: (A)

The concept at work is a potentiometer, a three-terminal variable resistor. It has two end terminals that span the full resistive track, so the resistance between those ends is the maximum for that element. The third terminal is the wiper, a movable contact that slides along the resistive strip and taps off a portion of the resistance. By moving the wiper, you change how much resistance is between the wiper and each end, which lets you vary voltage or current in a circuit. This matches the description of having three leads with two tied to the ends (maximum resistance) and a third lead connected to the wiper as it wraps around the resistor. The other options describe configurations that don’t provide this three-terminal variable-tap arrangement.
