​

Answer 1

Answer:

answer is a. I am sure

pls mark me brainliest.

Answer 2

Step-by-step explanation:

In the given fig:−

In parallel resistances, the potential differences across them is same.

potential difference across PM

V=4×1=4volt(i.e,across4Ω)

Equivalent resistance of lower side arm,

R

eq

=1+

0.5+0.5

0.5×0.5

=1.25Ω

Let current I flow in lower branch,

So, 1.25I=4V

I=

1.25

4

=3.2A

therefore,

3.2A currents flows in 1Ω resistance,

hence potential difference between M and N is

V

′

=3.2×1=3.2volt

Hence,

option (B) is correct answer.
