Answer to Question #332392 in Electrical Engineering for Alannd

Question

The current i (in amps) t seconds after closing the switch in the circuit shown is given by: i(t) = V/R(1-e-(R/L)t) Consider the case where V = 120 volts, R = 120 Ohms and L = 0. 1 henry. Find the time tm required for the current to reach 99% of its final value, then use linspace to create a vector t having 10 elements with the first element 0 and maximum value tm. Calculate the current i for each value of t from part (a). The length |u| (magnitude) of a vector u = given by |u| = x2+y2+z2. Given the vector u = 23. 5i - 17j + 6k, determine its length two ways:
