Why does more current flow through copper wire than a reed switch?

Ideally the reed switch should be able pass as much current as the wire supplying it.
A voltage drop across the switch would indicate resistance and suggest that the maximum rated current has been exceeded.
Reed switches are delicate and should only switch small currents. They are used where actuation by a magnet is required, without mechanical interference.
To switch larger currents a relay should be used, fed from the reed.

Why does more current flow through the bulb when the reed switch was replaced with copper wire?
Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current.
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
How does a voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.
Electrons flow freely through a copper wire is what?
this is your homework. i know because i have this question on my homework too. its very confusing!
Why is copper commonly use to make electric wires?
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.

How does push to make switch work?
Push-To-Make switch is a switch in which pressure is applied to the switch for it to let the electricl current flow through.
In a circuit the purpose of a switch is to?
In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
How are electrical current and circuits related?
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
What happens when we switch on the tube light does current flow through it or voltage?

A switch is a device that stops and starts current flow in a circuit?
Yes, a switch is a device that stops and starts current flow in a circuit.
What can stop the flow of electricity?
That is the job done by a switch. When the switch is 'on' the two contacts in the switch are touching, which allows current to flow. When the switch is 'off' the contacts are not touching and no current can flow. In small switches the power to alter the contacts comes from the user's finger. A switch never absorbs power, because there is always either no current passing through it, or no voltage across it. That makes electronic switches very useful in circuits.
What is a material that allows current to easily flow?
A conductor is a material that allows current to easily flow.
What happens if the switch is open?
If the switch is open, current does not flow.
IF you want to stop a current flow through a device device three in the circuit which one of the following single switches should you open?
If you want to stop the current flow through Device 3 in the circuit, the switch that should be open is Switch S5. When an electric current flows through a long conductor, each free electron moves through a relatively short distance.
What materials will conduct the flow of electricity?
While electricity doesn't flow, current does. Conductors are materials that allow the electrical currents to flow through them. Metals are the best conduction, such as silver and copper.
