The available apparatus includes a battery, a switch, a variable. My Investigation I choose to do a nichrome wire because during my preliminary work nichrome shows more resistance compared to nickel and copper wire. Introduction dans une dissertation de philo can be constantan wire sometimes.
Extracts from this document. Property Information Resistivity Overview.Wire type/diameter Resistance (W) Copper mm W. Constantan mm W. Constantan mm 5 W. Constantan mm W. Diagram: The things that I will measure and observe are the voltage running through the wire and the current.
This will allow me to calculate the resistance of the wire.3/5(2). GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by.
Gcse Physics Coursework - 27 mm and 0. 48 Resistivity Of Constantan Wire. Thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using.4/4(1).
Im doing my resistance of a wire coursework and ive done all of it apart from the last bit where i have to describe how the experiment testing the resistance of a wire could be used in a workplace. I have to give a use for the experiment in a workplace and describe how the experiment is used ina workplace and expalin why it is useful.
Wire type/diameter Resistance (W) Copper mm W. Constantan mm W.
Constantan mm 5 W. Constantan mm W. Diagram: The things that I will measure and observe are the voltage running through the wire and the current. This will allow me to calculate the resistance of the wire.3/5(2). A gauge wire is wider than gauge wire and thus has less resistance.
The lesser resistance of gauge wire means that it can allow charge to flow through it at a greater rate - that is, allow a larger current.
Thus, gauge wire can safely support a circuit that uses an appliance drawing up to 20 Amps of current.
