• An ohmic resistor with a previously unknown resistance is attached to a 9.0 V battery, making a simple circuit. The current is measured to be 6.3mA by an ammeter attached to the battery. 
• 
  
• A.) What is the resistance of the resistor? 
• 
  
•  B.) What is the resistance of this same resistor when attached to a 6.0 volt battery after the 9.0V battery?
