While an inductor is being energized the current flowing through it as a function of time is:
i(t) = 56 (1 - e(-4600 · t) ) mA, for all times t > 0 and t is in seconds.
What is the inductance, if a voltage drop of 1.188 V is measured across this inductor at time t = 0.5 ms.
A resistive temperature sensor is modeled as R(T) = 100 +0.0039(T-25)+1.0x10^-5(T-25)^2 where T is in degrees C. Calculate the tempco and sensitivity at T = 50 degrees C.
