Solving an RL circuit For the drawn circuit, take both the light bulb and the resistor to have resistance R, the inductor to have inductance L, and the battery to supply voltage ɛ. At time t=0 the capacitor is uncharged and the switch is closed 12 to complete the circuit. You should work this problem out on a different sheet of paper. 1. The three chosen currents in the circuit have been labeled on the picture with plausible directions chosen. 2. What will the voltage difference across the inductor be in terms of L and dl3/dt where la is the current in that section and if we travel from right to left?

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…
