one side of an oxygen meter is exposed to oxygen in equilibrium with a mixture of Ni and NiO at 1300K, and the other side is exposed to air at 101kPa. If the cell e.m.f is 0.596V, Calculate the standard free energy change at 1300K for the reaction 2NiO+O2=2NiO
the donor energy level is approximately 0.1 ev below the conduction band. the approximate value is calculated from the binding energy equation from hydrogen. derive the binding or ionization energy which is equal to the total energy.
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
Design a MOS differential amplifier to operate from +/- 1V power supplies and dissipate no more than 2 mW in the equilibrium state. The differential voltage gain Ad is to be 5 V/V and the output common-mode dc voltage is to be 0.5 V.
A knight is riding across a 12.0 m uniform drawbridge as shown in the figure. The right end of the bridge is held up by a cable and the left end is supported by a hinge. The mass of the rider and horse is 355 kg and the mass of the bridge is 493 k..
Build a series circuit consisting of a 130 V 60 Hz ac source, a 5 ohm resistor, a 53.05 mH inductor, and a 0.33156 mF capacitor. a) Draw the ac circuit diagram b) Sove for the phasor current and phasor voltages across each component.
Design a tunk circuit with resonant frequency of 10 kHz and bw of 500 Hz. show your design equation, then use a circuit simulator package to prove your design is correct. you must attach both your design calculation and computer output.
