Time domain simulation not working

I am new to circuits and to circuitlab. I am trying to use circuitlab to help me with a course in circuits I am taking

I made the following circuit with a switch to see how the charge across the capacitor changes over time.


When I try to use the Time Domain to simulate it I get back Solver returned no data.

What am I doing wrong?

There are two problems in your sim.

Please see:


And you have a constant current source in parallel with a capacitor. It is not well documented in CL but it is likely that CL assumes that the current has been applied for all time prior to the start of the sim so the voltage across the cap will already be infinite at t=0 (the start of the time domain sim) so the simulator probably throws an error.

Thanks for the reply. I am new to all this and every bit helps.

I will look over those and see if I can't get this working
