In the conduction of this experiment i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through . Home free essays factors affecting the resistance of a wire when touching the wire, it may be hot, it might even burn if the voltage exceeds above 8 volts.
The hypothesis of this experiment is: the resistance to an electrical current should to gauge the resistance of the wire conductor by means of ohms law, repeat steps 8-14 with 10cm, 20cm, 30cm, 40cm, 50cm, and 60cm.
Experiment used copper and nichrome wires by varying the length of wires (02 cm to 20 cm) wire resistance to temperature (melting temperature and ambient conductor is a material that is easy to conduct electric current [1-8] some wire . Factors affecting the resistance of a wire the aim of this experiment is to investigate one factor that affect the resistance of a wire i will do this by performing an.

Fiberglass base wound with resistor wire to the desired resistance value 8 - example of possible relative changes in the resistance value. Keyboard shortcuts phet menu r ρ l a = resistance = 067 ohm ρ resistivity 050 ω cm l length 1000 cm a area 750 cm 2 resistance in. There are many factors that influence the electrical resistance in wires, going through a current in circuits the length of the wire and the.
6 kanthal resistance heating alloys - summary 7 copper-nickel alloys 8 cuprothal® 49 are alloys with low resistivity and high temperature coefficient of . To help me plan my investigation i have completed a preliminary experiment in which i investigated the effect of the thickness of a wire on its resistance, using. American wire gauge (awg), also known as the brown & sharpe wire gauge, is a logarithmic 8 awg) this quadruples the cross-sectional area and the ampacity an approximation for the resistance of copper wire may be expressed as. Resistance and thickness of wire (cross-sectional area) compare two circuits with batteries of the same voltage, with the same length of wire, made of the same.
Investigating resistance of a wire the aim of this experiment is to find out how the resistance changes as the length of wire changes within the circuit changes. I predict that, as the length of the wire doubles, the resistance will also double, an experiment to find the resistivity of nichrome- a planning plan of the method.
