Resistance all conductors show this opposition to current flow is called resistance there are several factors that affect the resistance of a conductor smaller diameter wires have greater resistance temperature - heating a wire increases its resistance the effect of thickness is. The concept of resistance will be extended by looking at the factors that affect resistance in a resistor piece of resistance wire (110cm) long ammeter two 1,5 v cells metre ruler how does the length of the wire affect the resistance of the wire. For this project i want to investigate the factors affecting the resistance of a metal wire factors that effect the resistance of a wire are: length diameter cross-sectional area worked out from this. Free essay: aim: to investigate the factors that affect the resistance in a resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire more about factors affecting the resistance of wire factors affecting students behavior. Factors affecting resistance factors affecting resistance • temperature: in general, for metallic wire, the higher the temperature, the larger its resistance. The factors affecting the resistance of a piece of wire mitigation spacers.
resistance in a wire - phet interactive simulations. 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. What are the factors that affect resistance of a material/wire update cancel ad by amazon the resistance of a wire what are the factors affecting the resistance ask new question still have a question. What factors affect the resistance of a wire (2) nicola tregay mill chase school, bordon i can predict that the thinner the wire the higher the resistance if i had a piece of wire 1 mm in diameter and a piece of wire 2 mm in diameter.
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 variables variables that i am going to keep the same variables that i am going to change width- 036mm2 material- nichrome wire. This piece of wire has a large resistance compared to the resistance of standard electrical wire how will changes in these factors affect the total resistance of this piece of wire make a prediction such as, when variable x increases. I am going to investigate what factors affect the resistance of a wire there are three main factors which affect the resistance of a wire: these electrons travel at a steady pace, when they come to a different piece of wire, they have to slow down in order to be able to pass. Factors affecting resistance of a wire extracts from this document introduction factors affecting resistance the only way we would be able to solve the problem of the bends and twists in the wire is to use a brand new piece of wire and look after it very carefully.
How do the following factors affect the resistance of a wire and how please explain well: cross-sectional area, magnetism and material. Preet kaur: physics report- resistance myp5 ib download resistance 3 investigation task factors affecting the resistance of a wire research question does changing the length of a wire affect it's resistance background information there are few.
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. 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. Factors of resistance what is resistance resistance occurs when electricity flowing through a wire is halted, blocked, or slowed in some way there is something resisting the flow of electrons. Electrical power electrical energy is easy to move from place to place, using wire or cables the symbol for resistance is r, it is measured in ohms (ω) a hair dryer has a power rating of 920 w it is operated from the mains supply.
An investigation into the resistance of a wire free gcse physics using the same piece of wire throughout the experiment meant its areas of wires or even change the temperature of the wires deliberately and see how manipulating these variables affect the resistance of the wire.
Factors affecting wire what factors affect the resistance of a piece of wire what i am going to investigate is, what factors affect the resistance of a piece of wire. Class practical investigating the changing resistance of a wire as it heats up apparatus and materials power supply, low voltage, dc eg 12 v, 4 a at least temperature change and resistance class practical investigating the changing resistance of a wire as it heats up apparatus and. Four factors affecting resistance posted on october 3, 2010 october 3, 2010 by john vagabond variable resistors or potentiometers control the length of wire we introduce into a circuit - the volume control on a hi-fi. Electrons slow down as they travel through a wire because they hit the fixed atoms of the conducting metal in an occurrence called resistance the longer the wire, the fewer electrons are able to. Variables affecting electrical resistance consistent with the discussion above, this equation shows that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. 123helpmecom/searchasptext=voltagevoltage then a piece of wire with a smaller resistance what factors are going to change the amount of current going through the wire will change as the length. I shall look at various factors which can affect the resistance of a wire and investigate one of these in greater detail i shall start off with theory on resistance and use it to make a prediction and then plan and carry out an experiment to obtain enough evidence to prove or disprove my prediction.
