Determine the form of the particular solution for the differential equation2
2dv(t)/dt + v(t) = 5tsin(t)
Then, find the particular solution. (Hint: The particular solution includes terms with the same functional forms as the terms found in the forcing function and its derivatives.)
An electronic PID temperature controller is at steady state with an output of 12 mA. The set point equals the nominal process temperature initially. At t=0, the set point is increased at the rate of 0.5 mA/min (equivalent to a rate of 2 deg F/min)..
A silicon abrupt junction in thermal equilibrium at T= 300k is doped such that Ec-Ef = 0.21eV in the n region and Ef - Ev = 0.18eV in the p region. Determine the impurity doping concentrations in each region.
professor patt is trying to decide when he should shave his beard. your job is to design a logic circuit whose output
Electricity is distributed from electrical substations to neighborhoods at 15,000 Volts, to a transformer on utility poles near homes, where is it stepped down to 120 Volts for household use.
A three-phase, wye-connected, 220-V, 10-hp, 60-Hz, six-pole induction motor has the following parameters in ohms per phase referred to the stator: R1 = 0.294; R2 = 0.144; Xn = 0.503, X12 = 0.209;XM = 13.25.
