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.
What else can I help you with?
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
What is the current carrying capacity of silver wire?
The current capacity varies depending on the length and diameter of the wire
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.
When a wire with a current is placed in a magnetic field what happens?
The wire magnetics will make move attract or repulse see speakers
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What happens to the resistance of a wire as it's length increases?
Other things being equal, a greater length will result in more resistance.
What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
How Does the length of the wire affect its resistance?
As the length of the wire increases, the resistance also increases. This is because a longer wire offers more opposition to the flow of electrical current compared to a shorter wire. Resistance is directly proportional to length, so doubling the length of the wire will double its resistance.
When a wire is smaller the resistance increases What happens to the electrical current?
increase
What is the relationship between current and length of a wire?
The relationship between current and length of a wire is inversely proportional when the resistance of the wire remains constant. This means that as the length of the wire increases, the current flowing through it decreases, and vice versa. This relationship is described by Ohm's Law, where resistance (R) is directly proportional to length (L) and inversely proportional to current (I).
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What property of a wire increases when it is made thinner?
It's resistance to electric current increases.
What happens to the current in a filament is replaced by a longer wire?
If a longer wire is used to replace the filament, the resistance in the circuit will increase due to the longer length of the wire. This increase in resistance will cause a decrease in current flowing through the circuit, which can affect the overall performance of the system.
What property of wire increases when it is made longer?
Its length, obviously. But also its electric resistance.
How does the resistance of a wire vary with its lenght?
The resistance of a wire increases as its length increases. This is because as the length of the wire increases, there are more atoms for the electrons to collide with as they pass through the wire, leading to more opposition to the flow of electric current and a higher resistance.
