I built a basic schema with resistor, capacitor, ground and a battery in LTspice and MicroCap. I used transient analysis mode.
I expected to see on a chart decreasing current and increasing voltage during launch fixating at 0A and battery voltage eventually correspondingly, but I got flat lines where capacitor voltage is battery voltage from time = 0 and current 0.
I wanted to prove time to charge rule for capacitor where T = 5RC.
I played with various time ranges and time steps and no luck.
What I am doing wrong?
