Resistance of a wire - gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons the number of. Class practical a simple investigation of the factors affecting 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') current only flows through a component of a circuit if a potential difference (voltage) is put across it the bigger the potential. The end of their lab coursework, students should be able to design, assemble, and use basic electronic circuits and have the skills necessary to measure 4- wire resistance measurements using a dmm ohms law to the left four-wire ohms or kelvin measurements bypass the voltage drop across rl by bringing two high. Section in the coursework b grid on the cover page of the coursework booklet or mark the candidate nominated investigation according to the agreed criteria enter the marks for each section in the coursework b grid on the cover page of the coursework booklet tsal science (revised) 2009 –marking scheme page 2 of.

Waves on a string (or wire) with length, tension, and mass per unit length of string apparatus and techniques diagram students decide on instruments (and ranges), and the gauge and length of resistance wire used after preliminary experiment teacher suggests link between resistance and dimensions of a metal. First before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which would be the most effective and easiest factor to measure below is a list of. Physics coursework title 2017 changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance part 1 ( introduction) (i) statement or problem to be investigated what eg: multimeter readings fluctuating –loose connections in wires,cracks in play doh, play doh dried out. What are molecules made from bonding mechanics essay geiger-marsden experiment essay making sense of data - solar cells essay to investigate what factors affect the strength of an electromagnet essay experiment: to investigate the factors that affect the resistance of a wire essay what affects the resistance of a.

The independent variable is the one that we change (eg by changing the length of resistance wire) the dependent variable changes in response (eg the resistance increases) the control variable, which is kept constant to make sure that it's a fair test if you were measuring temperature rise with the power of a heater,. Physics gcse coursework: factors affecting the resistance of a wire ali hlaiyil introduction: before starting my coursework i have decided to choose 2 factors that will affect the resistance of a wire i will do this by going through all of the factors that affect the resistance of a wire and how i would measure each factor to find.

- If the original wire had a resistance of r ohms, each of the cuts has resistance r/ 3 ohms putting 3 equal resistors in parallel results in a resistance of 1/3 of their individual resitances so the final resistance is (r/3)/3, aka r/9 i suggest you try to study your coursework closely getting other people to do your homework won' t.
- Physics coursework - resistance plan what affects the resistance of a piece of wire there are many variables in this investigation the resistance of the wire could depend on: the voltage from the power pack the voltmeter the ammeter the length of the wire the piece of wire used ie the material it is made.
- Resistance of a wire data analysis coursework help for charter school year 10 how to complete the experiment.
- What the investigation is about your task was to find out how the length of a wire affected its resistance most of the resources and information you need are in the science shared area of the network before you started the experimental part you found out about the scientific reasons for resistance.

How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire current is the rate. In this piece of coursework you have to take careful measurements, with particular attention to the quality of the measurement and any inferences you can is it to measure a particular quantity (eg young' modulus), to establish a mathematical relationship between two variables (eg resistance and temperature of wire),. 1564 words - 6 pages gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons the number of.
