    dc current amplifier

    I need help in creating a dc current amplifier. The current/voltage source would be a battery. The amplifier could be multi-staged. I would like the output current to be in the range of 50 - 100mA, and the input current being in the range of 5 -10 mA. It will be driving a small electric...

    Power consumption of network printer?

    Funny thing is I can't find any detailed electrical specs on HP's website, which I thought was odd. Another note is that we normally put network printers on their own branch circuit. Don01, that is interesting about 30% of power consumed is from standby appliances. Let's say you had a very...

    Power consumption of network printer?

    For an HP network printer (your average firm's small laser printer), what VA rating would you use? We actually hooked up a power meter and found that it took about .3A in standby mode, but while processing a job it varied between 3 and 8 amps. My supervisor came to the conclusion that the NEC...
