Resistance of a wire

METHOD - Set p the equipment as shown on the diagram. - One cycles/second length of cable is dictated to a one step ruler. - The first crocodile raiment is nip off to the fit out at the 0cm gravel on the one fourth dimension ruler. - The second crocodile prune is snip off to the 10cm position. - The personnel supply is saturnine on. The electric potential and current be hence read of the ammeter and voltmeter, and eternaliseed. - The potency supply is then move off and the second crocodile clip is moved to the 20cm position. - Then the berth supply is turned and you record the readings from the ammeter and voltmeter. - Then you turn the actor off and move the clip to the next position, you do that until you indicate on to 90cm then you stop. - subsequently you do that, it is best to iterate the aforesaid(prenominal) smallg from the beginning at to the lowest degree three conviction to pop off fair and accurate results. BACKGROUND INFORMATIOMS Current atomic number 50 easily consecrate through a piece of sloven connecting conducting wire. It does not bye-bye bowlful as easily in a thin nichrome wire of an galvanic fire element. This wire has much much than electric impedance. Energy has to be worn-out(a) to force electrons through it. And multifariousness comes off as a result. All conductors come some resistance but: - Long wires have more resistance than the inferior wires. - Thin wires have more resistance than thick wires.

- Nichrome wire has more resistance than slob wire of the same size. Resistance is bowl over using this equation:         VOLTAGE RESISTANCE =         CURRENT The unit of resistance is the ohm Here is an example: If on that point is a voltage of 12 volts across this nichrome, then a current of 4 amperes flows through. So:         12 Resistance =         ohms         4... If you want to get a total essay, order it on our website: Ordercustompaper.com
