1. Here is that in-class problem reprised plus, a second example. You should review your notes from that day’s class, as well as Section 24.5 and the associated assigned problems: Ch.24: P 47, 49, 51 Quiz# 3 As mentioned Wednesday, Oct. 15 as we worked out in detail a simple AC series RLC circuit: "This is EXACTLY the kind of problem you’ll find on your NEXT quiz!"

2. A series RLC circuit has a resistance of 25.0 , a capacitance of 50.0  F, and an inductance of 0.300 H. If driven by a 120v, 60Hz source, find: (a) the impedance of the circuit. (b) the current in the circuit. (c) the phase angle between current and voltage. (d) the rms voltage drop across each component. (e) the power dissipated in the circuit. (f) What f would make this circuit completely resistive? (g) What would the power dissipated in the resistor be then? X L =113.1  X C = 53.1  Z = 65  1.85 A +76.3 o V R =46.25v V L =209v V C =98.24v 85.67 Watts 41 Hz 576 Watts

3. A series RLC circuit has a resistance of 250 , a capacitance of 3.50  F, and an inductance of 0.600 H. If driven by a 150v, 60Hz source, find: (a) the impedance of the circuit. (b) the current in the circuit. (c) the phase angle between current and voltage. (d) the rms voltage drop across each component. (e) the power dissipated in the circuit. (f) What f would make this circuit completely resistive? (g) What would the power dissipated in the resistor be then? X L =226.2  X C =757.9  Z = 587.5  0.255 A -64.8 o V R =63.8v V L =57.6v V C =193v 16.28 Watts 109.8 Hz 90 Watts
