Re: Conditionals - IF, ELSEIF, etc.
Hello Grant, if(condition, value for true, value for false) Example: if V(4)>2 then 5 else 1 Bv-source V=5+3*if(V(4)>2, 5,1) Best regards, Helmut

Conditionals - IF, ELSEIF, etc.
Hello, I'm trying to understand the use of conditional statements for LTspice but haven't been able to either find a good definition or example where an IF...THEN.. type conditional statement is used.

Re: current source and charging/discharging capacitor
In SPICE, a current source is an ideal current source, like a voltage source with infinite impedance. When a current source is set to 0 amps, its current is 0 amps, at any voltage. Really. So yes,

Re: current source and charging/discharging capacitor
Ah, I get what you're saying. Is there any other way to simulate what the experiment does? In the paper in question they charge at constant current and then they disconnect the source, thereby

Re: current source and charging/discharging capacitor
Hello, I wonder about this test circuit " testing the paper's experiment.asc". Since when does it makes sense using a switch in series to an ideal curernt source? Please think about that this is

current source and charging/discharging capacitor
Hi, I'm trying to monitor the charging and more importantly discharging of a capacitor that is connected to a resistor and constant current source. I want to charge the capacitor for 5 seconds at 4A,
