Question

For questions 1 and 2, please refer to the following figure. OLTAGE At which point should you measure the "cold" resistance of the lamp? At which point should the resistance of the lamp? How do you determine the resistance at each point in the curve? 1. 2. 3. Under what conditions is a resistor considered "linear" (follows Ohm's law)? a. b. c. d. The resistor and wire is physically straight, not curved The resistance is directly proportional to the current The resistance is the same for any resistor current The resistance is inversely proportional to the resistor voltage . Which of the following is NOT recommended when building a circuit? a. b. c. d. e. Make the circuit appear like the circuit diagram Both lab partners should at all times participate in the actual building of a circuit Add meters to the circuit after the basic circuit is laid out Turn on the power supply only after the circuit has been checked by the instructor Use red wires from the positive supply terminal and black wires to the negative terminal TIME 5. For the figure above, which item is

Explanation / Answer

(1) Not enough information.

(2) To find the resistance at each point, take the ratio of voltage to current at the point.

(3) The resistance is the same for any resistance current.

(4) Add meters to the circuit after the basic circuit is laid out.

(5) B represents the maximum current.
