Amperage Gain Using an Op Amp

Hi, i just want to know if it is possible.

Currently i got an output Voltage of 4.5v and a Current of 20mA from a digital potentiometer.
I just want to adjust or boost the 20mA to a higher current value using an Op Amp.
Please Help me.
Thanks,

Hi,

Yeah it's possible. You can increase the current using op amp. The average current's formula is:

Av = 1 + R2/R1
