| Sep 11, 2022 at 12:07 | comment | added | Andy aka | @AnayChadha when you ask a simulator to plot the current through a resistor i.e. I(Rx) then what direction does the simulator use as the correct direction for current? How does it know whether you mean flowing from top to bottom or bottom to top? Read what the guys are saying. | |
| Sep 11, 2022 at 12:00 | comment | added | Anay Chadha | When I ask it for the current in the resistor then it plots the same graph for current in the negative y-axis. What is happening? | |

| Sep 11, 2022 at 11:42 | comment | added | Anay Chadha | If I reverse the diode connection the sign for voltage when the diode is conducting changes. However, the current is still positive. So does current never become negative when a diode is there in the circuit? | |
