An AC power supply produces a maximum voltage ? V max = 102 V. This power supply

Question

An AC power supply produces a maximum voltage

?Vmax = 102 V. This power supply is connected to a resistor R = 23.0 ?, and the current and resistor voltage are measured with an ideal AC ammeter and voltmeter as shown in the figure below. An ideal ammeter has zero resistance, and an ideal voltmeter has infinite resistance.

(a) What is the reading on the ammeter?
(?) A

(b) What is the reading on the voltmeter?
(?) V

Explanation / Answer

Known Values:
?Vmax = 102 V
R = 25

Equations:
V=IR
I=V/R

Solution:
V=(102)/(?2)
V=72.12 V

I=V/R
I=(72.12)/(23)
I=3.135 A
