Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points An AC power supply produces a maximum voltage of 160 V. This power supply is con- nected to a 24 resistor, and the current and resistor voltage are measured with an ideal AC ammeter A and an ideal AC voltmeter V, as in the figure. V A E = E max sin t E max = 160 V S 24 What does the voltmeter read? Note: Re- call that an ideal ammeter has zero resistance and an ideal voltmeter has infinite resistance. Answer in units of V. 002 (part 2 of 2) 10.0 points What is the reading of the ammeter? Answer in units of A. 003 (part 1 of 3) 10.0 points An rms potential difference of 121 V is placed across a light bulb with a resistance of 11 . What is the rms current in the light bulb?...
