I am getting wrong value for Power calculation

I have attached image of my diagram.

I am getting voltage and current values as expected. but active power value is different. since it is pure resistor, active power = rms current* rms voltage also I noticed that when I change the discrete sampling time in power gui block, the power value changes. Please help me, I have no idea. I am very new to simulink.

Thank you

It appears that the wrong block is used to compute the power. Power (Phasor) will compute active and reactive powers using voltage and current phasors. However, the simulation is not set to Phasor simulation. Instead the Power block should be used in this context.
