Question

you have gone to Mumbai for a press conference bit you come to know about its cancellation after reaching there. write an email to your mother about your return program​

Answer 1

Correct option is

D

1Ω

Effective resistance of 2Ω and 2Ω in parallel R

AB

=

2+2

2×2

=1Ω

∴ Equivalent resistance between P and Q, R

PQ

=2∥(1+R

AB

)=2∥2

⟹ R

PQ

=1Ω
