    On schematic above determine the current drain on the battery with no load on the output terminals. With a 10K load, what is the current from the battery?

    To determine the current drain on the battery with no load i just found total resistance 18.3K and than found current in the circuit I=22V/18.3k=1.2mA
    I need help to find current from the battery with 10k load. How will circuit look like with 10k load? Thanks.

    Did the schematic have an output line with a letter on it, which you forgot to draw?

    Odds are that it did...

    Sorry yes i did miss output lines, here is how it looks like:

    So basically to find current drain from the battery with a 10k load i just have to place that 10k load on A and B terminals? Than I'd have to find total resistance with that 10k load and from that find total current?

    Either that, or it could be that it wants you to hook it up, once in A and Ground and then in B and Ground. Read the question carefully.
