  3. Speaker Interference / Induction from mains cables

    Home Theater
    Hello, I've got a problem with what I think is inductance from mains cable into the speaker cable. When I short the speaker cables with everything off I'm getting a pop through the speakers. When I ran the cables I tried to keep them separate but I obviously didn't leave enough room. I don't...

  7. determining wattage usage of electronics

    Electrical
    I'm familiar with the amps x volts = watts. On many electronics, however, it gives a range for the volts, maybe 100-240 volts and then something like 1 amp for the current. Is this saying that the wattage in, say, Africa is higher than in the US? If it pulls 1 amp no matter, then would it be...

    I have one outlet in my laundry room with a dedicated 20-amp breaker. My 230V washer specifies it needs a 30-amp and my 120V dryer specifies a 15-amp.
