Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
1An instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
- ‘Chloride content of the cold acid extract was determined using a selective ion electrode potentiometer.’
- ‘Install potentiometers, hook them to the accelerator pedal and connect to the controller.’
- ‘The controller reads the setting of the accelerator pedal from the potentiometers and regulates the power accordingly.’
- ‘Other evaluation tools include surface electromyography, accelerometers, potentiometers, handwriting tremor analysis, and long-term tremor records.’
2A variable resistor with a third adjustable terminal. The potential at the third terminal can be adjusted to give any fraction of the potential across the ends of the resistor.
- ‘There are no switches, jumpers or potentiometers to set.’
- ‘The controller uses two stock joystick potentiometers, plus another potentiometer that measures the draw on a cable that emerges from the body of the controller.’
- ‘The potentiometer that measured the knee flexion angle was initialized with the knee at 90 [degrees] of flexion.’
- ‘If you don't know, it's basically a potentiometer which alters the relative bass/treble of the sound.’
- ‘Therefore I mounted on the axis of the potentiometer, a capacitor as a knob, and a small switch next to it.’
- ‘It has its own fan controller; a potentiometer regulates the fan speed.’
