| Dec 9, 2018 at 17:17 | comment | added | TimWescott | Circuit simulators deal with idealized wires, which have zero resistance (and zero inductance, and zero capacitance). To model a real-world circuit that looks like what you drew on paper, estimate the resistance of each wire and put resistors into each leg in the circuit simulator. | |
| Dec 9, 2018 at 17:07 | comment | added | The Photon | The two parallel pieces of wire are modeled as ideal, not as 100 mOhm. So it can't tell how much current flows through each wire. | |
| Dec 9, 2018 at 17:06 | comment | added | Stdugnd4ikbd | @ThePhoton, But in real life, if there will be, for example 5V voltage, an 100 Omh resistor(as shown in circuit) and amperemetre(don't know how it's in English), in one of parallel wires what will it show? | |

| Dec 9, 2018 at 17:01 | comment | added | The Photon | Yeah, Falstad will want to know the current in each wire so it can do its cutesy animations. In this circuit, that can't be determined so Falstad will consider it an error. | |

| Dec 9, 2018 at 16:58 | comment | added | Stdugnd4ikbd | @Andyaka why it doesn't work in a simulator? | |
| Dec 9, 2018 at 16:57 | comment | added | The Photon | Which simulator? It might just be upset that it can't determine how much current flows through each wire. | |
| Dec 9, 2018 at 16:56 | comment | added | Andy aka | Why something is wrong "physically" has little relationship to why a circuit won't work in a simulator. | |
