Question

In an RLC series circuit, the voltage amplitude and frequency of the source are 100 V and 500 Hz, respectively, and R = 510 Ω, L = 0.23 H, and C = 2.7 µF.

(a) What is the impedance of the circuit (in Ω)?___________Ω

(b)What is the amplitude of the current from the source (in A)?_________A

(c)If the emf of the source is given by v(t) = (100 V)sin(1,000πt), 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) = __________

(d)Repeat the calculations with C changed to 0.27 µF.

Z= _________Ω

I₀=_________A

i(t)=____________
