For a RL Circuit having AC voltage source V=Vp Sin(ωt) and V=100 , R=1 Ω and L=0.1 H
The assignment is about plotting the current response for this circuit of the two instants of voltage zero-crossings and of the two instants of peak voltage with a given one cycle of sinusoidal wave.
I was able to get only the current response for the circuit while assuming frequency (f)=50 Hz but i don't know what plotting current response at zero and peak voltages mean or how to use Tina or Multisim to do.
I can choose the AC voltage source signal to be sine waveform with phase=0 but for Multisim i can only choose it to be sine or cosine so the result is different from Tina so is Tina the correct one or i'm wrong?
Anyone can help ?

You can set any initial phase of V1 sine signal. In properties of V1, in "Value" tab, choose "AC analysis phase:" and type your ω value that you need, in degrees (0, 90, 180, 270...).
In Transient, "Analysis parameters" tab, set "Initial conditions" in "Set to zero".

thanks!
When i change the phase (0,90,180,270) Current response doesn't change and is the same thing for Voltage , is that possible?
for 0 degrees

for 90 degrees
