lemme solve this
p= v²/r
r1=100/220*220
=1/484
same way r2=25/220*220
=1/1936
total r= 1/r= 1/484+1/1936
r= 387.2
v=ir
I=v/r
220/387.2
=0.57 A
p= v²/r
r1=100/220*220
=1/484
same way r2=25/220*220
=1/1936
total r= 1/r= 1/484+1/1936
r= 387.2
v=ir
I=v/r
220/387.2
=0.57 A

hope u understand
take this p= v²/r into consideration
