The earth return it is not only a resistive return but also a capacitive return using the capacitance of the earth itself. Again the symbol you are using it is not the symbol for earthing. | |

| Jul 13, 2015 at 6:13 | comment | added | Lavya | @IgnacioVazquez-Abrams What assumptions? an what will happen in practice if we make circuits like the above two? will they perform the same? (assuming earth is wet or whatever it takes for it to be at it's usual best conducting state. | |
| Jul 13, 2015 at 6:11 | comment | added | Lavya | @GRTech I am not talking about the common reference point here. In the first circuit, by ground I mean the literal insertion of the wire into earth. From Wikipedia ground article, for example: "In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.". I am taling about the last type -"a direct physical connection to the Earth". Hence, my question is, will there be a difference if we connect the two end with a conducting wire vs via earth? | |
