Question

Question 22, chap 133, sect 3. part 1 of 2 10 points An AC power supply produces a maximum voltage of 170 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. 24 Emax = 170 V E Emax sin wt 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. Question 23, chap 133, sect 3. part 2 of 2 10 points What is the reading of the ammeter? Answer in units of A.

Explanation / Answer

Part 1:

Voltmeter reading = Emax = 170V

Part 2:

Ammeter reading = Emax/R = 170/24 = 7.08 A
