A wire is used to power a radio that is much too small for the current it is carrying. Using a voltmeter, a voltage drop of 0.20 volts is measured between the ends of the wire, which carries 5.0 amps (and gets warm). What is the resistance of this wire? Round to the nearest hundredth.
 
  What will be an ideal response?

Question 2

How much resistance is present in a 6.0-volt electric motor that draws 10.0 amps of current?
 
  What will be an ideal response?

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
