Explanation:
For R
1
: This is a equivalent wheatstone bridge circuit. The equivalent
resistance R
1
=R=1Ω.
For R
2
: The equivalent resistance R
2
=(
1+1
1
+1+
1+1
1
)
−1
=2
−1
=0.5Ω
For R
3
: The equivalent resistance R
3
=1+
(1+1)+(1+1)
(1+1)(1+1)
=1+1=2Ω
As P=
R
V
2
and V=3 for each so P∝
R
1
Thus, P
