Question

In meter bridge experiment, if value of known resistance R increases in one gap the balancing length corresponding to it will decrease
increase​

Answer 1

Answer:

For meter bridge:

Q

P

=

100−l

l

where P= unknown resistance , Q= known resistance, l= balancing length.

Thus, P=

100−l

l

×Q=

100−20

20

×1=

4
