    You need to keep in mind that mA represents milliamperes, or one thousandth of an Ampere. Does that help?

    isnt that ohms law? 2.66 mA is (2.66 X 10^-3 A), so just multiply that by the 5.92V and do dimensional analysis to convert the units. One volt is W/A and watts are J/s. If you multiply an ampere times a volt, the ampere will cancel and leave you with watts.

    multiply the numbers then the units will follow. W/A * A makes the A go away. All you have left is W.

    One Volt multiplied by One Ampere is one Watt.

    so convert 2.66 mA to .00266a right? or no? and multiple that by 5.92 which would be .0157472?

    move the decimal point 3 places, so 2.66 milliAmperes is equal to 0.00266 Amperes.
