rth = r3||(r1 + r2)
vth = vs.r3/r1+r2
vth = vs.r3/r1+r2

rth=120//(100+68)
vth=
vth = vs.r3/r1+r2
=ioo*120/(100+120+68)
vth=
vth = vs.r3/r1+r2
=ioo*120/(100+120+68)

Vth=v*120/288,
Rth=168*120/(120+168)
Rth=168*120/(120+168)

Vth = R3*(Vs/(R1+R2+R3))= 120*(100/(68+100+120)) = 41.67 V
Rth = R3//(R1+R2) = (120*160) / (120 + 168)= 70 ohm
Rth = R3//(R1+R2) = (120*160) / (120 + 168)= 70 ohm

From circuit
Vth=VR3/(R1+R2+R3);Rth=(R1+R2)//R3;
on solving ans is option D.
Vth=VR3/(R1+R2+R3);Rth=(R1+R2)//R3;
on solving ans is option D.

R1+R2+R3=R
I=V/R
Vth=IR
Rth= (R1+R2)/R3
I=V/R
Vth=IR
Rth= (R1+R2)/R3

By voltage devider rule Vth= 120*100/68+100+120
Nd Rth= (R1+R2)//R3
Nd Rth= (R1+R2)//R3

By voltage rule vth = 120*100/(68+100+120)=41.66
rth=120+100//68=70 ohm
rth=120+100//68=70 ohm
