Part (a): Calculate the power of a hair dryer that has a resistance of 14 ohms and operates at 120. volts. Show your work, and ensure that each numeric value has the appropriate units. Your answer should be rounded to the appropriate number of significant digits. Part (b): Watts, volts, and ohms are Sl units that can be expressed in the 'base' SI units as follows: kg-m2 kg-m2 kg-m2 watt = s3 volt ohm s3.A ' s3.Ą2 ' (Recall that 'A' is the abbreviation for an ampere.) Use algebra and the equation at the top of the page (P=V/R) to show that the base Sl units for watts equal the base Sl units for volts?/ohms. You do not need any numbers in this algebraic exercise.
