p = VL*I.
VL = 18*33/(33+70) = 5.76.
I = 18/(70+33) = 0.174.
p = 5.76*0.174 = 1.
VL = 18*33/(33+70) = 5.76.
I = 18/(70+33) = 0.174.
p = 5.76*0.174 = 1.

E = I(R+r).
I = 0.174,
P = I^2 R,
P = 1W.
I = 0.174,
P = I^2 R,
P = 1W.

This is maximum power transfer theorem
RT=RI+RL
RT=70+33=103 ohm
IT=Vs/RT
IT=18/103=0.174A
PL=I^2*RL
PL=1.00W
RT=RI+RL
RT=70+33=103 ohm
IT=Vs/RT
IT=18/103=0.174A
PL=I^2*RL
PL=1.00W
