Question

What will happen to the balance point if the value of the resistance connected in parallel to the cell is increased?

Answer 1

There will be no change in the balancing point value if a resistance is connected in parallel.Since the resistance in parallel increases, there is no change in the voltage resultant

There will be no change of the point at which balancing of the potentiometer is obtained. There will be no effect in voltage across the parallel network but current is diverted to the the parallel path.

Answer 2

Answer:

L2 will increase

Explanation:

see r=(L1/L2 - 1)R

since r is constant for a cell hence if we increase R then (L1/L2 -1)  will decrease this means either L1 decreases or L2 increases.

and we know L1 only depends upon e.m.f of cell and not R.

so L1 remains same

hence L2 increases.

if you don't know L1 and L2 then pls first go through the theory and procedure of this experiment first
