Applications of the 280 ohm rheostat
At 280 ohm the rheostat suits circuits with higher-resistance loads or smaller currents, where students use it as a potential divider to feed a variable voltage to meters, sensors and semiconductor devices, or in series to limit and adjust current.
- Potential divider for a variable supply to meters and sensors
- Current limiting for LEDs, diodes and small components
- Adjusting current in galvanometer and meter conversion experiments
- Characteristic curves at small currents
- College and senior-school electricity practicals
