1:13 AM ? loncapa1.fsu.edu .'ll AT&T;? Voltage and Current vs Time Graph LCR Circuit Part A The following graph shows the voltage and current through a single circuit element. What is the frequency of the ac generator? Vp 63.0 V, Ip 1.40 A, t1-0.0269 s :-. Voltage Current t(s Submit Answer Tries 0/15 Part B What is the average power dissipated in this element? Submit AnswerTries 0/15 Part C The circuit element above is either a resistor, an inductor, or a capacitor. Use the graph and what you know of circuit elements to determine what type of element is shown in the graph. If it is a resistor what is the value of its resistance? If it is an inductor, what is its inductance? If it is a capacitor, what is its capacitance?

Explanation / Answer

Given t1=0.0269

Time period=T

Till t1,1.75 cycle is completed

So T=0.0269/1.75=0.0153

Frequency=1/T=65.1Hz

Part B

Power dissipated=0 as element have voltage lead of 90 degree than current

Part C

As voltage leads current,it is inductor

Z=V/I=45

wL=45

L=0.158 Hz
