Hi,
i have a problem during connect the triac circuit to transformer as show.. . the ac volage at point 1 is 120V, let said if the triac is trigger on, the 120Volt will pass through the resistor. if we use multimeter to measure the voltage at point 2 and point 0, we should get back 120V rite? what i wan in this circuit is the resistor load will consume volt as what in point 1 after the triac is trigerred. in this circuit, triac is use as switch. what should i change to meet my requirement? thank for your help..

I don't see a ground reference anywhere in your simulation. That will cause a problem.
