Electrum broadcasting same transaction

[btcguys]

As the title suggests: is it possible to broadcast same signed transaction more than once in Electrum?

For example, let say a person, who has 5 BTC, signs a transaction from offline computer to send one BTC from address A to address B.
Can that same signed transaction be broadcasted 4 more times to send remaining 4 BTC from address A to address B?

Once a transaction sends BTC, it will be sent to addresses B and C where C is the change address.  A new transaction would then need to be created and signed by C to send the remaining funds.

The transactions in bitcoin actually send based on unspent outputs from previous transactions instead of just keeping a balance on an address.  Once a transaction output is spent, it can never be spent again, and the unspent outputs of the first transaction will be used to create new transactions.

Thank you. This is helpful!

Edit:
What if address is not changed to address C? for example what if address A still has some funds?

Thats not possible. Every input (former unspend output) has to be spend entirely*. You could use A as your changeaddress however. This would send the funds back to A. It wouldnt allow you to use the same TX though, since its a new unspend output with different properties.

*everything that is not spend will be considered a minersfee IIRC.

Thank you! This makes sense.

All funds from a single unspent output must be spent entirely in the same transaction (or miners fee), however if there are multiple unspent outputs on a single address, they can be spent separately.
