    Hi,

    Enclosed is my simple circuit. What is the purpose of 4000W / 1 Ohm connect in series with AC source? Can anyone help?

    Thanks

    If in case there is a short circuit in the unit being tested the 1 ohm 4000 W resistor will dissipate the power and will not damage the power source ? My guess would be that...

    an end use would likely give insight into the configuration. what mrmount said, or possibly current limiting for the device under test. Fuses for instance can be classed at 5Kamp.

    Possibly a means of indirectly measuring current. 1V/Amp. Of course the load would see that voltage deducted from the supply source voltage.
