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.

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.
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.
What is the formula of copper 1 sulfate?
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
What does a electrical solenoid on a winch do?
The same as in a car. The heavy current required by a winch motor can easily burn out a small switch .By operating a solenoid first you get a heavy duty switch operated remotely and closer to the winch terminals thus lowering voltage drops in the wiring.
What best descibes induction?
Inductance is the property of a passive circuit to produce a voltage that is proportional to the rate of change of the current through it. Inductance is defined by the formula: V = L di/dt So an inductor of 1 Henry develops a voltage of 1 v across it when the current through it is changing at 1 amp per second. This is why a DC circuit with inductance is difficult to switch off, because the inductance produces a high voltage when the switch is tripped (because the current is changing very quickly). In an AC circuit the alternative formula is: V = jwL. In this case w is 2pi times the frequency in Hz and the 'j' indicates a 90-degree phase advance in the voltage relative to the current (in the formula 'w' is normally written as a small Greek letter omega but we don't have a Greek font on here).
How does an electric circuit with a battery lamp copper wire and switch work?
The battery provides the current and the energy; the lamp consumes the energy when the current goes through it; the copper wire conducts the current; and the switch lets you close or open the circuit (so that current passes, or doesn't pass, through).
What is a vibration switch?
it is a switch,current goes through when switch is on and the current doesn't go through when its off you're welcome
What happens when a switch in a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens when a switch a current is opened?
current through the switch become 0.and switch become a high value resistor.
What are the uses of the relay?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
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.
When a light switch is turned on what travels through the wire?
Current flows through a wire when a light switch is turned on.

What a switch does?
What a Switch DoesA switch starts or stops current from passing through in order to turn electrical objects on and off.
What is on load and off load switching?
On load switching is when a switch can be operated whilst current is still passing through the switch (i.e. it is on load) Offload switching is when a switch is operated whilst there is no current through the switch (i.e. it is offload)
What is a static switch?
A static switch is a switch that uses the electrostatic current that flows through the human body to power on or off the device.
What is offload device?
an off-load device a a switch where there is no current passing through it when its switched, a isolator is a off load device, a light switch is a on-load device because there is current passing through it when its switched.
