Open Documentthe wire increases, the resistance of the wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much voltage is applied through them, these materials are known as ‘Ohmic’ resistors. This is because they are said to obey Ohm’s law, which states that if a voltmetre is used to measure the voltage (V) of an unknown resistance (R), and an ammetre is used to measure the current (i) through the same unknown resistance, then ‘R’ would be given...

Open DocumentInvestigating Ohm’s Law Introduction/Background Current is the rate of the flow of energy; an electric current is the flow of electrical charge around the circuit. It is measured in ohms (Ω). The quantity of flow in an electric circuit is dependent on the ohmic value of the resistance. The amount of resistance in a given circuit is stationary and is not dependent on the current. “The higher the voltage of a battery, the more potential energy per coulomb of charge it can supply.” (1) It is...
