Describe what factors affect the resistance of a wire, and how each factor affects the resistance the amount of charge that flows in a circuit depends on the voltage provided by the voltage source. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire these collisions slow down the flow of electrons causing resistance the four factors that affect the resistnce of a wire are:. There are many factors that are known to affect the resistance of a wire however, there are a few factors, which influence the resistance of a wire more than anything else one factor, which determines the resistance of a wire, is the material in which the wire is made out of as the . Factors affecting the resistance of a wire introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured . Factors affecting resistance 1 factors affecting resistancereported by: ralph lery guerrero kevin roxas marco lauro delos santos 3 factors affecting wire .
The diameter of the wire will have an affect on the resistance of a wire this is because the electrons have to squeeze together more to pass through a thin wire than they do to pass through a thick wire. The material of wire could also affect the resistance of a wire, as some materials may vary from one another the material must be chosen sensibly, as some materials may be more available, less expensive and easier in use than others. The 2nd and 3rd discussions were good but didn't discuss magnetism the 1st guy: an open circuit has infinite resistance even a straight piece of wire has some self-inductance (or self-magnetism) one affect of inductance is that it opposes changes in current so when you first apply a dc volt.
- factors which affect the resistance of a wire to start off this experiment i feel that it is suitable to explain the main facts of this study below is a section . The nichrome wire has a higher resistance than the copper wire and the longer the wire, the higher the resistance ohm's law states that the current flowing through the circuit is directly proportional to the voltage applied. Resistance lab report to investigate the factors that affect resistance the resistance of nichrome wire is higher than copper wire, with the .
Factors affecting resistance 3 resistance of a materialresistance of the conducting wires used in electric circuits varies with the dimension of the length and area, and depends on the material the wire is made of. What factors affect the resistance of a wire planning background electricity flows around a circuit in a current a current is the flow of electrons. Observe changes to the equation and wire as you play with the resistivity, length, and area sliders sample learning goals predict how changing each variable will affect the resistance. The resistance of a typical conducting wire is low when temperature is low and high when temperature is high the increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through a . Factors affecting resistance are followings [r= (ρl/a)] (i)larger the length, higher the value of resistance of wire (ii) lesser the resistivity of the material of wire, lesser is the resistance of the wire ie resistance depends on the nature of the material.
In this article i will investigate what affects the resistance of a wire electricity flows in metals metal wires are made of millions of tiny metal crystals, and each crystal’s atoms are arranged in a regular pattern the metal is full of free electrons that do not stick to any particular atom . Factors that affect the resistance of a wire the resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega and pronounced 'ohm'). Aim: to investigate the factors of affecting the resistance of a wire in this experiment i will be using a metal nichrome wire to show the resistance. Factors effecting the resistivity of electrical coefficient of resistance several metals exhibit the zero resistivity at temperature near to absolute zero .
Factors affecting resistance factors affecting resistance • temperature: in general, for metallic wire, the higher the temperature, the larger its resistance. Two factors that affect the resistance of wire are, the length of the conductor and the circular mill area of the conductor the third factor is the metallic element from whic h the conductor . Four factors affecting resistance posted on resistance is directly proportional to length so if a length of wire is doubled then /halved then its .
