Question

Your friend says that a battery supplies the electrons in an electric circuit. Do you agree or disagree? Defend your answer.

Answer 1

The battery supplies the force that pushes the electrons through the circuit. It has electrons in it that are pushed through the circuit but there are also electrons in the components prior to hooking up the battery.

So, my (your?) friend would be 1/2 right. The battery supplies some of the electrons in a circuit, but it's not the only source of electrons. Whether or not it "supplies" electrons is kinda irrelevant, it's the FORCE that the battery applies that is important.

Think of it as a water pump, and hooking it up to a hose with water already in it.

Answer 2

Electrons In A Circuit

Answer 3

the key to understanding the question is the word "circuit". For every electron the battery might "push" into the circuit, another must come back to the battery via the return wire. The battery is a source of energy that has the property of being able to cause current flow in the circuit. It is not a "donator" of electrons.

Answer 4

All "electrical energy" in an electric powered circuuit is via pass of electrons. The direction of pass is from destructive to beneficial. A battery produces electrons at it particularly is destructive terminal which flows via the electrical powered circuit ending up on the beneficial terminal. remember that electrons have a destructive cost and are repelled via the destructive terminal and have an interest in the beneficial terminal.

Answer 5

Disagree.

IF it created electrons the battery/circuit would become increasingly negatively charged, which isn't observed to happen.

The battery doesn't create the electrons (would require a heck of a lot of energy (E=mc^2)), but pushes them around the circuit like a pump. Voltage analogous to the force, current the flow.
