HI, why is the alternator on my Mondeo whistling when the front windscreen heater is on?

simple, the heated screen takes a lot of amps out of the battery to work so fast, which in turn puts a lot of load onto the alternator, put the heated rear on at the same time and the whinning goes even deeper sounding, it's nothing to worry about it's doing it's job
