What Factors Affect the Resistance of a Wire?
Planning
Background
Electricity flows around a circuit in a current. A current is the flow of electrons. Currents are measured in amps.
Voltage is the force which pushes electricity through a wire. Voltage comes from a cell or a socket. Voltage is measured in volts.
Electrical resistance is a measure of the degree to which a body opposes the passage of an electric current. (en.wikipedia.org/wiki/Resistance(electricity). Resistance is a force that slows down the flow of electricity.
Resistance is calculated by:
R = V/I
R = resistance, I = current and V = voltage. This is called "Ohm's Law". To find the resistance you need to have the current and the voltage. Resistance is measured in ohms (Ω).
Resistance of a wire can be affected by different things. They are what the wire is made out of, the length of......
