Problem 36P
(Ill) A 1.60-m-long FM antenna is oriented parallel to the electric field of an EM wave. How large must the electric field be to produce a 1.00-mV (rms) voltage between the ends of the antenna? What is the rate of energy transport per m2?

Problem 36P
(Ill) A 1.60-m-long FM antenna is oriented parallel to the electric field of an EM wave. How large must the electric field be to produce a 1.00-mV (rms) voltage between the ends of the antenna? What is the rate of energy transport per m2?
ANSWER:
Solution 36P
Step 1 of 2
Length of antenna = 1.6 m
RMS voltage at end of antenna = VRMS = 1mV = 1*10-3 V
Electric Field = ERMS = VRMS/l = 1* 10-3V /1.6 m = 6.25 * 10-4 V/m
