I am trying to simulate a resistance which varies with time, using several time-controlled switches.
I want the switches to close in sequence; SW1 at 1 second, SW2 at 2 seconds, and so on.
I want them to remain closed, so I have set "t Off" to zero on every switch. (I have also tried using very small numbers like 1n but the problem is the same)
However, I get spurious results. In the first example below all switches close on time but the measured current is nonsensical. In the second example (only one resistor has been altered) it appears one switch does not operate at all? What have I done wrong?
However,
