Problem 2 Problem: A capacitor is allowed to discharge through a 1002 resistor and the voltage across the capacitor is measured using a voltmeter and plotted below. (a)Write the equation for AVc(t), the voltage across the capacitor as a function of time, and give numerical values for any constants you introduce including the time constant 7. (b)Compute the capacitance of the capacitor. (c)How long does it take the voltage across the capacitor to decay to of its initial value? Solve the equation you wrote using the constants in part (a) instead of reading them off of the graph. 100 90 80 70 60 50 40 30 20 10 2 10 12 14 16 18 20 t (sec) Vc(t) (Volts)

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3. The first support should be installed at the wall. ft ( m) from 4. The second support should be installed at from the wall. ft ( m) 5. The final support should be installed at the wall. ft…

I have the answers fro my textbook they are not matching with the one that you send
