Describe how a battery can create a current in a conducting wire?

The battery produces a voltage; if a conducting wire - or any circuit for that matter - is connected, a current will flow according to Ohm's Law, that is, the current is calculated as voltage / resistance.

Does electric current create magnetic fields?
Yes, electric current does create magnetic fields

What causes the electrons to flow?
hi I'm Adrianna; i have to say it would definitely be a current because without the current it wouldn't be able to flow. Voltage, actually. The voltage is similar to the pressure in a pipe and is sometimes called Electro-Motive Force (EMF). The current is how much flow there is and would be analagous to the volume of water delivered, as in gallons per minute.
Which of these must be used to create an electromagnet?
coils of wire, iron, and electric current
How did nikola teslas accomplishments change the world?
One of the most important things he did was create AC current or alternating current. AC current is used in the light bulbs we use today.
What uses chemical reactions to create an electrical current?
A storage battery falls into that category. A load has to be applied to the battery before an electrical current will flow.
What particles create the electric current in a fruit battery?
An electric current is movement of electrons, no matter the source or cause.
What uses a chemical reaction to create an electric current?
An electrochemical cell, which is sometimes called a battery.
Does a battery use chemical reactions to create an electric current?
i really don't know for sure but i think its yes
Will a copper and a zinc electrode placed in an acid solution create a current?
yes, in fact they are used for a type of Voltaic battery.
How many minutes does a 45mah battery last?
That completely depends on how much current is used by the circuit or device that's connected to the battery. For example, if there is no circuit or device connected to the battery, and no current is used, then the battery lasts for quite a long time. But if you lay a screwdriver across the battery terminals and create great balls of fire, then the charge on the battery may only last for 1/2 second.
Why do scientists create new tools?
because it is necessary to the research they are conducting
How you could use a wire and a battery to create a manetic field?
Any current will produce a magnetic field. If you let a current pass through the wire, you got your magnetic field.Note: If you connect the wire directly to the battery, without any resistance, you'll most likely destroy the battery, due to a short circuit.
Why does potato work as a battery?
A single object is called a cell; a battery consists of multiple cells. It works because the potato can act as a electrolytic substance, allowing current flow. However, the potato alone does not actually cause the current or voltage; it is the metals you use, which create a galvanic reaction.
Why is a car battery so big?
Because it has to turn over a large engine. This takes plenty of cranking amps. To create that much amps takes a large battery with plenty of storage space for the current needed.
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
Can you touch a car battery with a wrench?
only if it's off The plastic body of the battery, or one of the terminals, yes, BUT... disconnected from the vehicle or not, DO NOT allow any metallic object to touch BOTH of the battery's terminals [Positive and Negative] AT THE SAME TIME. This is because that touching both terminals at the same time with any conducting metal such as a wrench will create a SHORT CIRCUIT, and COULD cause the battery to explode, throwing shrapnel and battery acid everywhere for several feet around the shorted battery.
