The negative terminal of the battery is often connected to this "Zero Volt" point, but we should not assume that it is. In your original circuit, you did not show the negative terminal of the battery connected to anything, so I have to assume that it is indeed not connected to anything. If you connected a ground symbol to the negative terminal, then I would assume that it was connected to the other ground symbol, but as is, the circuit is incomplete. | |

Isn't ground a replacement of the terminal end of a battery? what is the difference between ground and the negative end of a battery? why do people use ground? | |
