A rheostat,also called variable resistor helps us to variate/change the amount of current flowing in a circuit.
It is used in a circuit basically when doing experiments,
As they help in variating the amount of current, we can record different values of V and R,when we change the value of rheostat.
U can see the experiments in ur lab manual and see it's uses

Its generally ised to demonstrate ohm's law.

Yaa that's what I said
Used in recording different values 0f v and R on different current amount
