The electrical resistance of a wire or circuit is a way of measuring the resistance to the flow of an electrical current. A good electrical conductor, such as a copper wire, will...
Resistance in Series and Parallel Circuits
The resistance of any electrical device is defined by the expression, R=V/I, where V (volts) is the potential difference across the device and I (amps) is th...
Electric resistance is the opposition to the flow of current and results in the creation of heat. A material with very low resistance, such as copper, allows current to flow very e...
In this experiment I will be investigating how the resistance of a wire is related to it's length.
The scientific explanation for resistance in a wire, is due to the ...
Resistance of Wire
The aim of my investigation is to investigate how length affects the resistance of a wire. Resistance is measured in ohms and it occurs when the electrons travelling alon...
In physics, the resistance of a strand of wire is affected by four factors: the material of the wire, its thickness, its temperature, and its length.
In my experiment, our group chose to study the...
A components resistance is defined as a ratio of a voltage across it to the current flowing through it.
R = V/I
The unit of resistance is the ohm. A component has the resistance of 1 ohm if the cur...
How does the Length of a wire affect the Resistance"
To measure how the length of a wire affects the amount of resistance when an electrical current is passed through it.
How does the length of a wire affect its resistance"
This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go...
Investigation of the resistance of a wire
Factor to be investigated:
We are investigating whether the length of a wire affects the resistance on a complete circuit.
I predict th...
