Consider a series RLC circuit with R =15 , L = 200 mH, C= 75F, and a maximum voltage of

120 V. (a) What is the impedance of the circuit at resonance? (b) What is the resonance frequency

of the circuit? (c) When will the current be greatest—at resonance, at ten percent below the

resonant frequency, or at ten percent above the resonant frequency? (d) What is the rms current in

the circuit at a frequency of 60 Hz?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
