What happens to an electric current when the wire is made smaller?

Electric current as we usually describe it is the flow of electrons. Current is caused to flow by voltage, which can be looked at as "electrical pressure" that forces electrons to move. Currents can be made smaller or larger by decreasing the voltage across a fixed amount of resistance. As resistance is the quality of "resisting" or "limiting" current flow, we can change resistance to change current. For a give voltage, if we increase the resistance, we can make the current smaller, and if we decrease it, we can make current larger. In electronics, voltage equals current times resistance. E = I x R Also true is that current is equal to voltage divided by resistance. I = E/R As current equals volts divided by resistance, if we change one of them without changing the other, current will change. And in increase in voltage (with no change to resistance) will cause current to go up. The opposite is also true. Also, if we increase resistance (with no change in voltage), current will go down. And the opposite is true here, too.

∙ 6y agoIf wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.

What property of a wire increases when it is made thinner?
It's resistance to electric current increases.
The path that a electrical current travels?
A path that is made for an electric current is called a circuit. The two main components in a circuit are the load and a source which are combined with conductors and as a whole form a circuit.
What is condenser capacitor?
Because that is what a capacitor used to be called - a condenser.AnswerUsed in this context, the word 'condenser' is derived from the Latin for 'to make smaller'. Early capacitors, such as the Leyden Jar, were able to store separated electric charge in a much smaller volume than methods hitherto used. So early capacitors were called 'condensers'. In France and Germany the older term remains in use.
What is meant by DC motor?
Only a DC motor uses direct current, and the reason is that it is the only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronic equipment.
What are motor made from?
an electric motor is a copper winding or 3 separate windings depending on the phase, the copper winding is the centralised inside of a iron magnet, this is also how a generator is made instead of putting a current on you turn the windings to receive a voltage .
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What is an electric current made of?
It is made out of small particals, smaller than atoms called electrons.
What is made of electric current?
It is made out of small particals, smaller than atoms called electrons.
What happens to the electric current when the wire is made smaller?
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
Path made for an electric current?
A path made for an electric current is classified as a conductor and can come in the form of many shapes and sizes.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
What is a magnet made by electric current?
An electromagnet.
An electric current is made up of?
An electric current is made up electrons that are moving into a place that is usually positively charged. It moves towards an area that is positive to be able to neutralize that charge.
Which magnet made by an electric current flowing through wires?
Electromagnet.
What happens when electric current is produceds?
What Happens when a n electric current is produced?When electric charges are made to flow through a wire or similar material, they produce an electric current. When the electric current is produced it become's a continuous flow of electric charges through a material.Resources: I found this research information at:Discovery Channel SCHOOL, Go Online scLinks (nsta) The name of the website's to find more info is discovery.com and PearsonSchool.comYou can also find more information in this textbook: Prentice Hall Science Explorer.

What happens when an electric doorbell button is pushed?
A circuit is made and the bell rings.
