Question
Construction of a Parallel R, L, C Circuit and Measurement of Circuit Characteristics
1. Construct the circuit in Figure 1.
2. Set the function generator voltage to 2.5 V RMS and the frequency value to 550 Hz.
3. Turn the circuit on.
4. Record the current reading.
IS = _____________ (A)
5. Is this the same as the simulated and calculated value? ________ (YES or NO)
6. Measure and record the branch currents:
IR = ________ (A) IC = ________(A) IL = ________(A)
Are the current readings the same as your calculated and simulated values?
(Circle your answer)
YES NO
If you answered NO, explain why you think they differ.
7. Repeat Steps 2 through 6 with the frequency generator set to output at 1000 Hz.
IS = ______________(A)
IR = ________ (A) IC = ________(A) IL = ________(A)
Are the current readings the same as your calculated and simulated values?
(Circle your answer)
YES NO
Explanation / Answer
is=v/(r//wl///wc)
w=2*pi*f=3455.752
wc=3.45*10^-3
wl=3455.7528*47*10^-3=162.42
is=2.5/(r//wl//1/wc)
is=29.36 mA
ir=v/r=5.32 mA
ic=v*wc
w=2*pi*f=3455.752
ic=2.5*3.45*10^-3=8.64 mA
il=v/(wl)=2.5/(3455.7528*47*10^-3=15.4 mA
is=ir+il+ic
for f=1000hz
w=6283.185
wl=295.31
1/wc=159.155
is=v/(r//wl//1/wc)
is=29.49 mA
ir=5.32 mA
il=v/wl=8.4656 mA
ic=15.71 mA
ir=ir+il+ic
