Does someone know the consumption of voltage for computer and what kind of current computer use (AC or DC)? Also what usage have radio and telephone?
Thanks a lot
All computers contain a transformer/power supply which converts AC to DC-many new computers, with large display terminals and speakers connected can consume up to 400w-large SCSI hard disks run at up to 10,000 rpm.
Not sure about phones, but I do know that they actually run on batteries in normal operation, sort of a UPS, as it were. Radios, stereos can be determined by looking at the nameplate on the unit. Their consumption varies according to the speaker rating/volume. Some high end systems with monster speakers attached will actually deliver straight AC to them. They contain no transformer, and generate considerable heat. I believe they are known as Class B, with regular stereos known as Class A/B switching Amplifiers.
