Hi I am a first year electronic student, I am trying to simulate a simple RC circuit with a DC votage, and I get a straight line current, instead of a cure line current like this

what have I done wrong?

 

Did you check "Skip initial operating point solution" checkbox under

Simulate / Edit Simulation Cmd / ....

 

Thanks t_n_k, it works for me now, but can you explain what does it do for me please, as I have googled that but didn't come up something make sense for me.

 

I think this stops the LTSpice engine form computing the initial conditions on energy storage elements such as L's & C's as if the source had been applied to the circuit a long time before t=0 [start of transient solution].

 

You can also label the output node (call it "out", or whatever), and then add a spice directive .ic v(out)=0.
