Rs=5+p
I=0.2
v=5
V=IR
5=0.2(5+P)
5=1+0.2P
4=0.2P
P=20ohm
I=0.2
v=5
V=IR
5=0.2(5+P)
5=1+0.2P
4=0.2P
P=20ohm

as given in the question the resistance are joined in series
so equivalent resistance=R1+R2=5+p
I =0.2
V=5
now by using formula
V=IR
5=0.2(5+p)
5=1+0.2p
p=4/0.2=20
therefore value of p is 20 ohm.
