draw a diagram to show the rheostat used as a (1)fixed resister ,(2)variable resistor
Dear student,
Watch this image of rheostat
If this rheostat is connected between points A and B it will work as a fixed resistor, but if the same rheostat is connected between points A and W it will work as a variable resistor.
Regards
