The ammeter is designed to let 95% of the input curent flow through the shunt resistor. The moving coil's resistance is 10 2, and the shunt resistance is 0.004 2. The Table Q1 below gives the relation between the deflection and the mutual inductance of the ammeter.

- The displacement of an oscillating spring can be described by x = A cos(wt) where x = displacement at time t, A = maximum displacement, w = angular frequency, which depends on the spring constant and the mass attached to the spring, and t = time. Find the displacement, x, with maximum displacement A of 4 cm, for times from 0 to 120 seconds with increments of 30 seconds, and angular frequencies from 0.4 to 0.6 radians/sec, with increments of 0.1 radians/sec. The displacement for all combinations of times and angular frequencies needs to be calculated. Use meshgrid. Display your results in a matrix with angular frequencies along the top row and times along the left column like so (you may put zero, 0, or NaN, in the upper left corner:arrow_forwardDetermine the amount of current (mA) flowing in the circuit if the charge seen at any cross-sectional area of the copper wire is 0.0052 in 30ms what is the resistance R(Ω) given the applied voltage and calculated current flowing in the circuit v=12v I=?
