benavides (jjb2356) – homework 27 – Turner – (59130) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 (part 1 oF 3) 10.0 points An AC voltage oF the Form V = V max sin2 πft , with Frequency 62 Hz and maximum voltage 190 V, is applied across a 14 W light bulb. When the voltage is frst applied, what is the current through the circuit? 1. the rms current 2.0 3. the maximum current 002 (part 2 oF 3) 10.0 points When t = T 4 , where T is the period oF the applied voltage, what is the current in the circuit? Answer in units oF A. 003 (part 3 oF 3) 10.0 points What is the rms current in the circuit? Answer in units oF A. 004 (part 1 oF 2) 10.0 points An AC power supply produces a maximum voltage oF 125 V. This power supply is con-nected to a 33 Ω resistor, and the current and resistor voltage are measured with an ideal AC ammeter “A” and an ideal AC voltmeter “V”, as in the fgure. V
