Transcribed Image Text: In an RLC series circuit, the voltage amplitude and frequency of the source are 100 V and 500 Hz, respectively, and R = 520 0, L = 0.22 H, and C = 2.8 pF.
(a) What is the impedance of the circuit (in 0)?
776.8
(b) What is the amplitude of the current from the source (in A)?
0.120
A
(c) If the emf of the source is given by v(t) = (100 V)sin(1,000nt), how does the current vary with time? (Use the following as necessary: t. Assume i(t) is in amps and t is in seconds. Do not include units in your answer.)
i(t) =
(0.129)sin(1000t – 0.64)
(d) Repeat the calculations with C changed to 0.28 pF.
