AC – Part 3. Today – Continue with AC Problems Some new material from the chapter Quiz on Friday; Exams will be returned and reviewed. There is a new Mastering Physics Assignment that finishes the chapter. Continue with chapter. Monday – Electromagnetic Waves – Putting it all together.
An AC source with ΔVmax = 125 V and f = 25.0 Hz is connected between points a and d in the figure.
Calculate the maximum voltages between the following points: (a) a and b 62.8 V(b) b and c 45.6 V(c) c and d 154 V(d) b and d 108 V
What is the time average of this sine (AC) signal?
comes into your home??
120V is the ‘rms’ value. (Did you know that??)
Average = ZERO
A series R-L-C circuit is connected to a 120 Hzac source that has Vrms = 80.0 V. The circuit has a resistance of 80.0 Wand an impedance of 106 Wat this frequency.
What average power is delivered to the circuit by the source?
