Unformatted text preview: hopkins (tlh982) – HW08 – criss – (4908) 1 This print-out should have 11 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 4) 10.0 points The primary coil of a certain transformer has an inductance of 1 . 16 H and a resistance of 71 . 7 Ω. If the primary coil is connected to an ac source with a frequency of 93 . 4 Hz and a voltage of 150 V rms , what is the rms current through the primary? Answer in units of A. 002 (part 2 of 4) 10.0 points If the primary is connected to 72 . 4 V dc, what is the current through the primary? Disregard initial effects. Answer in units of A. 003 (part 3 of 4) 10.0 points In case 1, find the power dissipated in the resistance. Answer in units of W. 004 (part 4 of 4) 10.0 points In case 2, find the power dissipated in the resistance. Answer in units of W. 005 10.0 points An ac power generator produces 60 A rms at 4259 V. The voltage is stepped up to 1 . 59 × 10 5 V by an ideal transformer, and the...
