If the wire is increased what should happen to the diameter?
If the length of the wire increases its diameter decreases
How does the length of a wire affect the resistance?
Yes, resistance is directly proportional to the length, and inversely proportional to the cross sectional area. R = p*l/A. Where R is the resistance of the piece of conducting material, p is Greek letter rho, representing the resistivity of the material, l (lower case L) is the length, and A is the area.
Will a thicker or thinner copper wire of the same length allow more electric current to pass through?
A thicker wire will transmit more current
What will happen to the electromagnet when current flows in the wire around it?
A coil of wire in which current is flowing is an electromagnet. If to that arrangement you add an iron core, then the magnet will get stronger.
What would happen if the length of wire increase what happens to frequency?
frequecy will not change
What is the current carrying capacity of silver wire?
The current capacity varies depending on the length and diameter of the wire
Which is a better conductor between a short wire and long wire?
Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.
What happens to the current of the wire when the length increases?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
If the wire is increased what should happen to the diameter?
If the length of the wire increases its diameter decreases
What effects resitance in a current?
length of the wire effects the resitance
When two terminals of 4.5 Voltage battery are connected by 100 meters long wire. the current in the wire is 50mA what will be the current from the battery when the wire is shortened 50 meters?
-- The resistance of the wire is proportional to its length. -- When the length is reduced by 1/2 , the resistance is also reduced by 1/2 . -- Reducing the resistance across the battery by 1/2 causes the current to double. -- The new current is 100 mA. (Assumes zero internal resistance in the battery, and that the 4.5 volts doesn't 'sag'.)
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.

What is the Change in resistance of wire when its length is double?
Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
What will happen to an electric wire if a large current passes through it?
It will get hot.
What will happen to the electromagnet when current flows in the wire around it?
A coil of wire in which current is flowing is an electromagnet. If to that arrangement you add an iron core, then the magnet will get stronger.
