What happens to resistant if wire diameter is decreased?
If the wire diameter is decreased, the resistance of the wire will increase. This is because with a smaller diameter, there is less cross-sectional area for the electrical current to flow through, causing more hindrance and resulting in higher resistance.
What is an electric arc diameter as function of the current?
The electric arc diameter is directly proportional to the square root of the current passing through it. This relationship is described by the formula D = k√I, where D is the arc diameter, I is the current, and k is a constant factor. Increasing the current will result in a larger arc diameter, while decreasing the current will lead to a smaller arc diameter.
What happens to the resistance of a wire as its diameter increase?
As the diameter of a wire increases, its resistance decreases. This is because there is more cross-sectional area available for the flow of electrons, resulting in less opposition to the flow of current and thus lower resistance.
What determines the strength of a coil?
The strength of a coil is determined by factors such as the number of turns of wire, the type of material used, the diameter of the coil, and the current passing through it. Increasing the number of turns or the current will typically increase the strength of the magnetic field generated by the coil.
Does the thickness of wire affects the flow of current?
Yes, the thickness of a wire, also known as its gauge, does indeed affect the flow of current. Thicker wires have lower electrical resistance, allowing more current to flow through them compared to thinner wires of the same material. Thinner wires will have higher resistance, which can create heat and reduce the amount of current flowing through them.
Suppose you make a new kind of compact disk that is the same thickness as a current disk but twice diameter By what factor will the moment of inertia increase?
16
What are the factors that increase the magnetising force of an electromagnet?
-- diameter of the current-carrying winding around it -- number of turns of wire in the winding -- magnitude of the current in the winding -- material comprising the core of the magnet
What happens to resistant if wire diameter is decreased?

How big is a US half dollar?

How do you increase current in a battery?
we can increase the current in battery by using current amplifiers or chopper's s the easy way to increase the current in battery........
What happens to the resistance of a wire as its diameter increase?

Which current uk coin has a diameter of 3cm?
No current circulating British coin has a diameter of exactly 3 cm. The closest is the £2 coin with a diameter of 2.84 cm.
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
An increase in ocean salinity can increase what creating a current?
An increase in ocean salinity can increase density creating a convection current.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
How do you make a super power full electromagnet?
-- Use greater length of wire. -- Wind it into more turns around the coil. -- Decrease the diameter of the coil. -- Increase the electrical current through the coil. Each of these actions will increase the strength of the electromagnet.
