Physics 152 Lab # 5 Charging and Decay in RC Circuits Abstract: In this lab we used a probe to measure the induced voltage caused by different coils: single, Helmholtz, and a solenoid. Then we recorded that data to see if there was any varying induced voltage from points different points inside and outside the coils. By isolating the experiment and only moving the probe radially we were able to obtain the needed results. Questions: 1. For the single circular coil of wire along the axis, why do you plot V(x) vs. [1+ (x/R)^2]^(-3/2)? Can you find the current through the circuit from this graph? How or why not? Please attach the corresponding graph. You can use the graph because the induced voltage is proportional to the magnetic field, which relates to the equation B(x)/B(0)= (1/(1+(x/R) 2 )) 3/2 . The current cannot be found from the graph because it seems like there was a fair amount of variability in our results to create an R 2 of only 0.81. This means that the voltage wouldn’t even be that exact however you could solver for it by getting the slope you should have the average
