= 27. In an RLC series circuit, the voltage amplitude and frequency of the source are 100 V and 500 Hz, respectively, an R = 500 12, L = 0.20 H, and C 2.0uF. (a) What is the impedance of the circuit? (b) What is the amplitude of the current from the source? (c) If the emf of the source is given by v (t) = (100 V) sin 1000nt, how does the current vary with time? (d) Repeat the calculations with C changed to 0.20uF. Please respond to the following question; Give several examples of electromagnetic waves that are encountered in everyday life. How are they alike? How do they differ
