Answer 2

In the given circuit, suppose, r=10Ω

r

1

=10Ω

r

2

=20Ω

and, r

3

=50Ω

(Please refer the diagram.)

Now, r

1

,r

2

,r

3

are connected in parallel. Suppose, resultant of these three resistances is R

e

.

Therefore,

r

Hence, r

e

=

100

Ω

Now, resistances r and r

e

are connected in series.

Therefore, equivalent resistance in the given circuit, R=r+r

e

R=10+

270

Ω, which is more than 10Ω, but less than 20Ω.
