A 12V power supply should ideally read close to 12 volts when under load; however, it may show a higher voltage if it's not under load or if there's an issue with the multimeter used to measure it. Variations can occur due to factors like voltage ripple, measurement inaccuracies, or the specific design of the power supply. If the reading consistently exceeds 12V significantly, it may indicate a problem with the power supply. Always ensure to check the specifications to confirm acceptable voltage tolerances.

If you have a video camera and you have a wire that says DC IN what do you plug that in to on your computer or do you leave it out?

dc in sounds like a power supply port. the power supply will convert ac 110 volt wall current to dc current to power your device or possibly to recharge the battery if equipped as such. read your owners manual.

What should your digital power supply read too tattoo outlines?

Hopefully the artist that's teaching you to tattoo has gotten into this, but... There are a lot of things that go into finding the right power setting, from the model of power supply you have to the machine you have hooked to it to the needles you use to the way you tattoo. The only way you're ever going to know is to test it...so go buy a chicken (seriously, a whole raw chicken from the grocery store) and experiment.

Can you use a PC bought in the US in UK?

Check the back; if the power supply has a switch that lets you select the voltage the PC can be used either in the US or Europe. If it DOESN'T have the switch, read the manufacturers literature to see what's required. you may need to replace the power supply, depending on what you have.
