Need more info... What type of load?
Generally, if you are talking about an inductive load (motor,
transformer, etc. ) the current will be less by 20% at 60 Hz due to
increase inductive reactance. (Assuming the same voltage).
Given these conditions, the voltage will stay the same, but if you
have some sort of variable voltage control (such as a Variac), you
might be able to incrase the voltage to compensate and bring up the
decreased level of current. Other factors, such as whether the
insulation can take a higher voltage, also come into play.
Very general question!!!!!!!!
Answer: Depends on the circuit being supplied.
Further: Assuming that the voltage stays exactly the same and the
circuit involved is completely non reactive (that is; contains no
capacitance or inductance) the values of current flowing should be
exactly the same.
An example of a circuit that probably would have little or no
'reactance' could be an incandescent bulbs or a simple purely resistive
But like many things you need to explain the situation and why the
question is asked.
Rather like saying 'how many miles will I get to my gallon of
petrol/gasoline?", without specifying the type of country/terrain in
which you live and the type/weight/ of vehicle and the fuel used!
Provide more info and then we can get into, if necessary, the
mathematics and or practical answers.

Voltage and current will both reach their peaks more often.
You'll find that your computer still gets the same voltage and still draws
the same current.
Transformers that might have been on the borderline of saturating will no
longer be there.
Motors will run faster. And that can lead to some complications.
Inductive ballasts for HID/fluorescent lighting will be cutting the current
back to a lower level and some lights may not even function. Electronic
ballasts will probably be unaffected.
