The step response of a circuit is its response to a step input, u(t). Knowing the step response of a linear circuit is extremely valuable as we can figure out the circuit's stability. In this problem we will analyze the circuit in Figure 1 for the output

Physics
A wire is bent into the shape of an planar Archimedean spiral which in polar coordinates is described by the equation r=bθ. The spiral has N=100 turns and outer radius R=10 cm (R is the distance from point O to point T). Note that in the figure below we
