Define phase and phase difference?
Sources A and B emit long-range radio waves of wavelength 450 m,with the phase of the emission from A ahead of that from source Bby 90°. The distance rA from A to a detector is greater than thecorresponding distance rB from B by 87 m. What is the magnitude ofthe phase difference at the detector in rad?I dont know what im doing wrong?I take x/?=phase difference /360 degreesso the corresponding phase difference= 360*87/450 = 69.6degreehence the phase difference at the detector= 90+69.6 =159.6degree.then converting to rad, 159.6 (pi/180 deg) = 2.7855 rad but wileykeeps saying that this answer is wrong? please help.
An inductor and a resistor are connected in series across an ACgenerator. After the switch is closed,A) is current and voltage across inductor in phase?B) what is the phase difference between the current in the circuitand voltage a criss the inductor?C) what is the phase difference between the circuit current andvoltage across the resistor?
