- factors affecting the resistance of a metal wire 1 investigate some of the factors that affect the resistance of a metal wire the current and voltage will be measured and then v = ir will be used to calculate the resistance. To investigate the factors of affecting the resistance of a wire essay sample 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 when the length and width is changed. Wires carry electrical current in circuits ie the length of the wire, the cross- sectional area of the wire and the type of material in the wire several expressions link the factors together.
Resistance in wires occurs when the electrons travelling along the wire collide with the atoms of the wire these collisions slow down the flow of electron causing resistance resistance is a measure of how hard it is to move the electrons through the wire. - investigating factors affecting resistance of a wire aim --- investigate what factors affect the resistance of wire, however in this experiment i am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same.
R = resistance in ohms current is the rate of flow of charge the charge flowing in a wire is carried by the electrons that orbit the atoms that make up the wire as soon as a potential difference is applied the electrons generally drift in one direction (you can think of it as rolling down a slope. Determine the electrical resistance for each of the readings determine how length, cross-sectional area, and type of material affect the resistance of a metal rod factors affecting electrical resistance but metals are not perfect conductors, otherwise the wires in our toasters would not get hot in this experiment, you will examine. In this experiment, you will examine the factors that affect the electrical resistance of metals objectives in this experiment, you will collect potential difference and current data for a number of metal rods determine the electrical resistance for each of the readings. An experiment to investigate the factors which affect the resistance in a wire voltage is the electrical force, or pressure, that causes current to flow in a circuit it is measured in volts (v or e.
Objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the one i am investing is the length at constant temperature my objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire the factor i chose was length. Investigating the effect of length on resistance is common but some students may wish to investigate the effect of the thickness of wire in either case, different wires should be made of the same material.
Physics, science 1 investigation- experiment to find out the factors that effect resistance in a wire scientific basis an electrical current can pass through a metal because the electrons in the outer shell of the wires’ atoms are allowed to flow freely throughout the wire. Extended experimental investigation: electricity several expressions link the factors together resistance measured in ohms (ω) is found by ohm’s law, r=v/i v represents voltage, a measure of electrical the alligator clips were clipped together, so that the resistance of the wires of the.
The resistance r is the resistance wire (constantan nichrorome) that you will be trying to calculate set the power supply to 1v this limits the current through the wire in order to reduce any heating effect which may change the resistivity. Investigating the effect of length on resistance is common but some students may wish to investigate the effect of the thickness of wire in either case, different wires should be made of the same material students may need to know the conversion between swg (standard wire gauge) and wire diameter/radius.
