    I have a light in the kitchen, its a light under the cabinets. Im currently operating at 12v at 20w drawing 1.67a. I got this by using p=iv.

    Amps, Voltage etc

    Hi, I'd like to know if anyone knows any good sources to help understand amps, voltage etc better. The teachers at college haven't got in on the subject just yet. I don't yet fully understand the breakers and why different amps are needed for different circuits. Thanks, Anthony.
