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

By Voltage dider rule(vth) = 100 * 120/(60 + 100 + 120) = 41.66.
And rth = (100 + 68)/(100 + 68 + 120) = 70.
And rth = (100 + 68)/(100 + 68 + 120) = 70.

Yes, correct @Eee.
When calculating the Venin voltage is equal to open circuit voltage.

By using vtg division rule (Vth) = Vs * R3/(R1 + R2 + R3).
and Rth = R1 ll (R2 + R3).
and Rth = R1 ll (R2 + R3).

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.

I = 100/288 = 0.347A.
Rth = 120/(100+68) = 70.
Vth= 0.347 * 120 = 41.6 v.
Rth = 120/(100+68) = 70.
Vth= 0.347 * 120 = 41.6 v.

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

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

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)
