Dont copy paste need new SOLUTIONs.solve with diagrams with clean Handwriting or understanding solutions A single-phase 60-Hz power line is supported on a horizontal crossarm. The spacing between conductors is 8 ft. A telephone line is supported on a horizontal crossarm 6 ft below the power line. The conductors of the telephone line are AWG No. 14 solid copper (d = 1.6277 mm) spaced 2 ft between centers. The conductors of the power line are AWG No. 2 solid copper (d = 0.2576 in). Find the mutual inductance between the circuits and the voltage per mile induced in the telephone line if the current in the power line is 150 A.

A meeting hall in an organization is to be provided with a lighting installation. The hall is 30 m × 20 m × 8 m (high). The mounting height is 5 m and the required level of illumination is 144 lm/m2. Design a lighting system for the hall with the given data. Lumens/watt for 200-W lamp = 12 and Lumens/ watt for 500-W lamp = 16. Utilization coefficient = 0.6 Maintenance factor = 0.75 space/height ratio=1 Using metal filament lamps, estimate the following: Flux Luman output per 200 W lamp Luman output per 500 W lamp Number of 500W lamps required Number of 220W lamps required Draw the spacing layout of these lamps State the reason if any of these 2 lamps cannot be arranged in the hall with the given specification. What is the significance of ‘room surface maintenance factor’ and ‘utilization factor’ in the lighting design

Since R1=18.10Kohm, R2=67.58Kohm, RC= 1.08Kohm, RE= 3.23Kohm, VCC=14.00V, Beta=241.00 in the circuit given in the figure, calculate the IC current by doing a complete analysis. When performing your operations, 2 steps will be taken after the point. choose the closest one from the stylish ones according to the +/-10% margin of error. There is only 1 correct answer to the question.
Use any method to calculate the current I1, if R = 9 and Vs = 3
