Expert Answer:

Magnitude of AC voltage/current is not  same as the instantanious value of the AC voltage/current.
Magnitude of the AC voltage/current is the rms value of voltage/current.
consider a 230 V AC mains supply used in many countries around the world. It is so called because its root mean square value is 230 V.
While the instantaneous value of voltage/current is the value of voltage/current at a perticular instance of time that varies with time. Its becomes max at paek voltage and also becomes zero.
