Relationship between the length of wire and its electric current?
Wiki User
∙ 13y ago
The electrons in a conducting wire are loose and can move freely. When the circuit is closed, a potential difference is set up across the terminals. The battery maintains this potential difference. Then the electrons in the wire move towards the positive terminal of the battery. This flow of electrons constitute the electric current.

∙ 12y agoThe size of the conductor depends on the current flowing through it and the insulation determines the voltage. Also when designing an electrical system, the size of the conductor also depends on the length of the transmission required.
So I would say increasing length will not have that much of an effect on voltage (except for some drops and some capacitive effects), however it will effect the current because increase in length increases resistance, so current starts decreasing.

∙ 11y agoWith an increase in the length of wire, there is an increase in both voltage and resistance. As a result of these inhibitors, the current decreases with an increase in wire length.

What is the relationship between the size of the electric current passing through a length of wire and its heating effect?
The relationship is that as the current passing through the wire increases so does the heating effect in the wire. To see its effect just use the formula: W=I2R R is resistance in ohms I is current in amps W is the heat output in watts Hope this helps
What is the relationship between wire size length of run and voltage drop?
The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.
How long is a high mass?
There is no direct relationship between length and mass.
What is current electricity measured in?
The SI Base Unit of electric current is the ampere(symbol: A), which is defined in terms of its magnetic effect, as follows: 'that constant current which, when maintained in two straight, parallel, conductors of infinite length and negligible circular cross-sectional area, and placed one metre apart in a vacuum, would produce between them a force equal to 2 x 10-7 newton per metre of length.'
What is the relationship between earth day length and the distance from the sun?
There is no direct relationship between the rotation of a planet (which governs day length) and a planets distance from the sun. The nature of the planets spin is more to do with the formation of the system early on, by large impacts of the more numerous bodies that would have been around.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field

How do you size the conductors feeding an electric crane?
Current draw and length.
Why is a cascode current mirror better than a simple MOSFET current mirror?
In simple MOSFET current mirror, the load current does not follow a linear relationship with reference current (ie for short channel MOSFET's multiplying factor due to channel length modulation cannot be neglected). But by cascoding the output resistance can be increased and since output resistance follows an inverse relationship with lambda (channel-length modulation parameter), the multiplying factor due to channel length modulation reduces to one and a linear relationship is obtained between reference and load current.
What are the 5 fundamental quantities?
Mass, length, time, temperature, and electric current.
Name Length of wire wound in a spiral to conduct electric current?
it is known as coil
What is the relationship between wire size length of run and voltage drop?
The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.
What is the relationship between the deflection of the wire and the current?
the relationship between the deflection of the wire and the ccurrent is when the voltage is 12volt the current become higher.Another AnswerPresumably you are referring to the force on a conductor placed in a magnetic field? In which case, it is equal to the Flux Density of the field (in teslas), the length of the conductor within the field (in metres), and the value of the current passing through the conductor (in amperes).
What property of a wire increases when it is made thinner?
It's resistance to electric current increases.
What is the relationship between the height and the base of a triangle?
There is no relationship. Knowing the length of one of them doesn't tell you the length of the other one.
What is the relationship between length and width?
They are just dating.
What is the relationship between the length of the radius and the length of the diameter?
The radius is excatly half of the diameter
