    Change the current from a voltage source?

    So what I understand so far, if I want to have 16 A out from a voltage source (230 V RMS) which is 325.269 V in amplitude (peak), can I simply add an resistor in parallel to achieve that? R = 325.269 V / 16 A = 20.329 ohm Do you think guys if I am on the right track? So if I am want simply to...
