How does length of wire affect resistance

WebV. I X R. To work out the voltage: current x resistance. To work out the current: voltage / resistance. To work out the resistance: voltage / current. Ohm’s law is shown as: V = IR. The length of a wire: The length of the wire will make a difference. This is because when you have a long wire, the electrons have to squeeze together for longer ... WebJul 7, 2024 · when you have longer length of wire, the current has to travel more distance, more the distance higher the number of obstacles it faces through its path. Therefore resistance increases with the length. When cross sectional area increases the space of the elctrons to travel increases (simply explained).

WebMoving your electronic products and security software from conception, to design, to test, and industry acceptance compliance. 3y WebMy prediction is that as the length of wire increases, the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire, which makes the electrons harder to flow through the circuit.

WebNov 20, 2024 · The thicker the wire, the lower the resistance. (3) Material: the material the wire is made out of will affect the resistance. Different materials have different resistivities, which is the ability of the material to allow electrons to move. It is dependent on electronic structure and temperature. WebResistance of the Length of a Wire at a Constant Temperature The aim of this experiment is to investigate how the length of a wire at a constant temperature affects the resistance of electrical circuits Variables: Independent variable = Length of resistance wire, L Dependent variable = Resistance, R Control variables:
