Quick Note! Today’s questions are based on the printed passage you will receive shortly. After reading your passage individually, choose the best answer to each question. You may refer to the passages as often as necessary. You have 4 Minutes to read your passage!

11 th Grade Science #1. In Experiment 1, the time constant of the circuit was the time required for the voltage across the capacitor to reach approximately 7.6 V. The time constant of the circuit used in Experiment 1 was: A.less than 12 sec. B.between 12 sec and 24 sec. C.between 24 sec and 36 sec. D.greater than 36 sec.

11 th Grade Science #2. If, in Experiment 2, a 1.5 x F capacitor had been used, the time required for the voltage across the capacitor to reach 6 V would have been closest to: A.4.2 sec. B.7.0 sec. C.10.5 sec. D.15.0 sec.

11 th Grade Science #3. The main purpose of Experiment 3 was to determine how varying the: A.battery’s voltage affected the resistor’s resistance at a given time. B.capacitor’s capacitance affected the time required for the voltage across the capacitor to reach a set value. C.capacitor’s capacitance affected the voltage across the battery at a given time. D.resistor’s resistance affected the time required for the voltage across the capacitor to reach a set value.

11 th Grade Science #4. Consider a circuit like that shown in Figure 1. Based on Experiments 2 and 3, the voltage across the capacitor will reach a given value in the shortest amount of time if the circuit contains which of the following capacitances and resistances, respectively? A.0.1 x F, 0.3 x 10 7 Ω B.0.1 x F, 1.0 x 10 7 Ω C.1.2 x F, 0.3 x 10 7 Ω D.1.2 x F, 1.0 x 10 7 Ω
