Can a ground wire tie into an other ground to ground it,. can say the ground from audio be grounded to the batt. ground, or other spot you know is grounded hope this makes sense. |

Kirchoff's law on a closed loop works on DIFFERENCE of electrical tension, called voltage, and so does not require a ground. Some simulators require an explicit ground so they can then speak of the voltage "at a" point, the second point, required to obtain the difference, being then, that ground. You can have different ground. An unconnected voltmeter, as an example, may have its ground anywhere. Same for a battery. You chose the ground where it is the most convenient for you. If you joint together multiple unconnected circuits, they can have only one ground, so you may want to re-adjust their voltage "at a point", but the difference between two points is not affected. If you a connected to the household electrical supply, you have a ground defined by the supplier, unless you wish to work with an offset of all the electrical tensions. You can also define a ground about electromagnetic waves that you get from an antenna. |
