Question

In Ohms law experiment the given resistance R is cut into two equal parts and parallel combination of this two parts are connected in between points X and Y in given circuit diagram. The net resistance between the points X and Y is

3 points



Your answer

​

Answer 1

Answer:

i ) Equivalent resistance between the points A and C

The resistance of AB and BC arm are in series so,

R

′

=2 Ω

Now this resistance is in parallel with the 2 Ω,

R

t

=

2+2

2×2

=1 Ω

ii ) Current in the circuit

I=

R

V

=

1

2

=2 A

iii ) Potential difference between A and B

As current divides equally, current in upper branch is 1 A,

so, Potential difference between AB is,

V=IR=1×1=1 V
