How do you calculate a resulting VCPD voltage if you have a Kelvin probe energy diagram and Kelvin probe's work function in 7 eV? Let's say we have two metals: one metal has a work function of 7 eV and another metal has a work function of 3.2 eV. How would you calculate the VCPD voltage?

Need help for parts (d) and (e). Thank you.

Specify the LM-series linear regulator required to regulate a fixed voltage of 17 V. Please write the numbers only in the answer field: i.e. for LM1234, you would write 1234 in the answer field.

(Full Solution). Examine each one of the following response functions to see if it is possible to cancel the zero with a pole. If it is, determine the approximate response, percent overshoot, settling time, rise time, and peak time.

The input to a full-wave rectifier is 20 V AC (RMS). The load resistor is 20 ohms and rectifier losses are 4W. The ripple factor of the rectifier is: O A. 0.96 OB. 0.33 O C. 0.48 O D. None of the other choices are correct O E. 0.75

Ex. 1633. A 120VAC_RMS 60Hz line is connected to a Triac with a firing angles of 114 degrees and 294 degrees. What is the RMS voltage at the Triac output? This is the function of a modern dimmer switch. Hint: calculation can be simplified by considering only the first half of the sine wave. ans: 1

A J- type thermocouple is used to measure the temperature in a heating process. The length of the air gap is 12mm and thickness is 0.2mm. If the thermal conductivity of material (K) is 0.025W/m-K, density of the material is 1.2 kg/m3 and specific heat capacity is 1005 J/kg-oc. Find the time constant of the air. Time constant of the bare material is, T=

A Si pn-junction at 300 K has an n-side resistivity of 35 2 and a p-side doping level of N,= 1×106 cm at equilibrium the value of the contact potential barrier of the junction wvill be: Select one: OA. 0.5821 V B. 7.617 V CC. 0.07309 V D. 1.001 V E. 22.39 V

C = 93 | F = 14 | G = 39 | S = 85 For the sinewave, give the following six values. Must give the UNITS after each number.  a. Vp (the peak voltage) b. Vpp (the peak-to-peak voltage) c. B (the DC bias or DC offset) d. T (the period) e. f (note that f will be a number of Hertz between 0 and 1 and your answer might have to be rounded OR you can choose to write it as a fraction), and f. θ, which is the phase shift in degrees in the expression Vpsin(ωt - θ) + B   Vp =  Vpp =  B =  T =  f =  θ =
