Resistance Of A Wire

Resistance of a fit out
Resistance
Resistance can be defined as a force which opposes the flow of an electric genuine (electrons) ab issue circuit. So energy is required to push the electrons around the circuit. The circuit can also resist the flow of electrons if the aloofness of the telegram used is long or the cross sectioned area is large.
The unit of safeguard is measured in VA-1 or Ohms (Ω) and the formulae of resistance can be represented as this:
RESISTANCE= VOLTAGE
CURRENT

What I am tying to find out is whether the thickness of a wire will affect the resistance of the wire. What I am going away to measure in this try out is the thickness of the wire and the resistance it gives. I am going to do this by measuring the thickness of the wire exploitation a micrometer.
The variables which will affect the resistance are:

1. distance: as the length of wire increases the electrons crosswise it will extradite to travel a longer distance and in that unconscious process the electrons will take a longer time to melt down across the wire. Hence an increase in the length of wire will make the resistance increase.

2.



Temperature: if the temperature in the wire is increase the atoms in the wire will vibrate more thusly causing more collisions, which makes the atoms pass in the way of the electrons. With this on that point would be an increase in resistance.

3. Material: The type of visible used would affect the movement of electrons that are allowed to flow with the wire .If the atoms in the material are jammed unneurotic ,then their would be more collisions therefore increasing the amount of resistance.

4. cross-section(a) area: As the cross sectioned area increases, electrons across the wire has more space to move about and slight collisions resulting in less resistance .Therefore as the cross sectional area of a wire increases, the resistance in the wire will decrease.

The variables (temperature, material and length) will have to...If you want to unhorse a full essay, order it on our website: Ordercustompaper.com
