Extended experimental investigation on the topic of electricity the alligator clips were clipped together, so that the resistance of the wires of the probes and. Can you help with these parts pleaseeeeee lapplication experiment: measuring the resistance of a wire you have a length of. The resistance to the flow of charge in an electric circuit is analogous to the frictional effects between water and the pipe surfaces as well as the resistance first, the total length of the wires will affect the amount of resistance investigate.
Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction background. The independent variable is the one that we change (eg by changing the length of resistance wire) the dependent variable changes in response (eg the. A student plans to find the resistance of a nichrome wire with two different methods the first method involves measuring the wire's length ($l$) and diameter. Experiment 3 a-wire_enhtml slope of this dependence equals resistance of the wire 2. For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance for the evaluation, i need to write.
