Q. A transmitter is connected to an antenna by a transmission line for which ¯ Z0 = R0 = 50 . The transmitter source impedance is matched tothe line, but the antenna is known to be unmatched and has a re?ection coef?cient
where RL (= ¯ ZL) is the load impedance. The transmitter produces a power of 15 kWin the incidentwave to the antenna andwill be destroyed due to overheat if the re?ected wave's power exceeds 2 kW. Determine the antenna's radiated power in this case and comment on whether the transmitter will survive.
Applications of Hall Effect: (i) To determine whether semiconductor is of n type or p type. (ii) To determine carrier concentration. (iii) Measurement of carrier mobili
A four-pole, three-phase inductionmotor is energized from a 60-Hz supply. It is running at a load condition for which the slip is 0.03. Determine: (a) The rotor speed in r/min.
Athree-phase, 440-V, 60-Hz, four-pole induction motor operates at a slip of 0.025 at full load, with its rotor circuit short-circuited. This motor is to be operated on a 50-Hz supp
