You have shown a battery as your voltage source, yet you have labelled it '8.5V AC'. This is a misnomer. A battery supplies a DC voltage. If you are refering to DC then your question is valid and the current would reach 63% of its final value (where final value=8.5/1500, ie. 5.7mA), in the period of one time constant.

You cannot apply the charging time of a time constant, to an AC waveform.
