Read this full essay on resistance of wire investigation (length) i predict that the longer the piece of wire, the greater the resistance will be 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. Free gcse physics coursework essay an investigation into the resistance of a wire - gcse physics coursework prediction i predict that the longer the wire , the larger the resistance this is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow. Revised on 3/6/2018 resistivity objectives: a to find the resistivity of a wire of unknown material b to study the relationship of resistance with area of cross- section and length of the wire apparatus required: multimeter connecting wires meter stick assembly with metallic wires theory: for a given wire of fixed length,. Resistance in a wire free essay example: how the resistance of a wire is affected by its length this investigation will determine how changing the length of the the shortest measured length of 10cm acquires the least resistance, therefore my prediction suggests as the length increases the more resistance generates.
Physics 2007 sample assessment instrument and indicative responses extended experimental investigation: electricity this sample is intended to inform the resistance of a conductor will decrease if its length and temperature remain constant method wire lengths (independent variable) of 20 cm, 40 cm, 60 cm and 80. Predictioni predict that as the length of the wire decreases so will the resistance this is because through a resistance of a 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.
1 user(s) rated gcse physics science coursework: resistance of wire experiment i predict that the readings on the voltmeter and ammeter would be higher but when divided and the resistance worked out that the resistance would be very similar to that of the results worked out in my main experiment. To the people taking their gcses in 2017, do you have all of the coursework titles i know: biology - factors that affect breathing rate physics - resistance in wires chemistry - if anyone knows the chemistry title for ocr 21st century a science then please say, because our school is going through it so. Controlled assessment tasks for gcse physics require candidates to: • develop hypotheses and circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) teachers may wish to current x resistance candidates should know how to calculate cross sectional area of wire from the radius.
A circuit with a cell and two lamps has high resistance and low current a circuit with a cell, switch, lamp and ammeter connected in series the resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current the relationship between resistance and the area. Gcse physics specimen assessment materials for first teaching from september 2011 for first assessment from summer 2012 for first award in summer 2013 explain why sonar would not be an appropriate method for this (d) the resistance of a piece of wire depends on its length and its cross- sectional area (i.
Resistance of a wire - physics coursework gcse extracts from this document i also predict that the longer the wire the more resistance it will show resistance is the force that opposes the flow of an electric current round a circuit so energy is needed to 'push' the charged particles round the circuit the larger the.
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. Before starting my coursework i have decided to choose a factor that will affect the resistance of a wire preliminary method in this preliminary experiment, i will use different lengths of wires to measure their resistance the main idea of doing the preliminary experiment was to find a suitable current number to put the. I will investigate how the length of the wire affects the resistance below are my results from the preliminary experiment (see table 1) how the length of a wire affects its resistancein my physics coursework i am results: length of wire (cm) test no voltage (v) current (a) resistance (w) free resistance of.
