Consider a resistor that is 5.0 mm in length and is part of a larger circuit you have previously measured that there is exactly 2.4 milliamps of conventional current (positive charges are moving) flowing through the resistor. There are colored bands on the resistor in the following order: BLUE-VIOLET-RED-(GAP)-SILVER.  (We won't need the uncertainty/tolerance information, so you can ignore that.) What is the resistance of the resistor in ohms? You can ignore the tolerance/uncertainty part. I just want the resistance. Someone comes along and arbitrarily decides that the terminal of the resistor where current is flowing INTO has an electric potential value of 8.28 volts. (Since potential is completely arbitrary, there's nothing wrong with this choice.) Using this choice, what is the value of electric potential at the end of the resistor where current is flowing OUT? (Hint: The answer is not 16.08 volts.) What is the magnitude of the electric field inside the resistor, assuming it is uniform?

Question
  1. Consider a resistor that is 5.0 mm in length and is part of a larger circuit you have previously measured that there is exactly 2.4 milliamps of conventional current (positive charges are moving) flowing through the resistor. There are colored bands on the resistor in the following order: BLUE-VIOLET-RED-(GAP)-SILVER.  (We won't need the uncertainty/tolerance information, so you can ignore that.)

    1. What is the resistance of the resistor in ohms? You can ignore the tolerance/uncertainty part. I just want the resistance.

    2. Someone comes along and arbitrarily decides that the terminal of the resistor where current is flowing INTO has an electric potential value of 8.28 volts. (Since potential is completely arbitrary, there's nothing wrong with this choice.) Using this choice, what is the value of electric potential at the end of the resistor where current is flowing OUT? (Hint: The answer is not 16.08 volts.)

    3. What is the magnitude of the electric field inside the resistor, assuming it is uniform?
