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
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...

Resistance of Wire
Planning
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...
