Resistance investigation coursework

Full investigation teacher gives students a full method with clear instructions as to how to set up the apparatus all instruments and measurements are specified and experiment fully specified teacher suggests outline method to determine resistivity by measuring resistance of wire but does not provide a circuit diagram. 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. An experiment to investigate the factors which affect resistance in a wirewhat is resistancea potential difference (v) applied across a wire of length (l), there is in the conductor, an electric field (e) in this electric field the free electrons are. Physics using conductors made of children's play (modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance. 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.

Whole investigations were introduced to gcse courses which gained a bad reputation because there were many vague criteria that were officiously applied to assess success whole investigations the independent variable is the one that we change (eg by changing the length of resistance wire) the dependent. Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction background research outlined and referenced firstly i researched this topic in my science book i found relevant information in my book about resistance, such as the fact that. A secondary school revision resource for aqa additional gcse science about resistance and electricity. Coursework a a 0 draft pro forma booklet for the assessment of junior certificate science biology reference mandatory investigations and experiments date completed ob3 carry out qualitative food tests current, potential difference (voltage) and resistance, and establish the relationship between them ref code.

This week i've been blogging about the resistance to required ethics coursework one sometimes sees in stem disciplines so, as a thought experiment, let's entertain the hypothesis that, by your twenties, your moral character is fixed -- that you're either ethical or evil by then and there's nothing further. Class practical a simple investigation of the factors affecting the resistance of a wire.

School science support 2016-2017, topic coursework b 10 physics title: using conductors made of children's play (modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the conductor length and. 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.

When the area of the wire increases the resistance will decrease, they are inversely proportional investigation plan my plan is to take a range of wires with different swg numbers and to measure their electrical resistances i will measure the resistance of 3 different lengths of wires and calculate the. Investigating how different lengths of wire affect the resistance in a circuit hypothesis: i predict that the longer the wire, the more resistance there will be so if the length of the wire were to double, so would the resistance the reason for my prediction is: the flow of electrons is called a current, the electrons are constantly.
