Student 1. The following are five problem statements for which you must select the correct physics equation needed to solve the problem based on the given information. You must complete at least four of the five problems. You are allowed to answer the fifth problem for extra credit. For each problem, you must select one of the 15 equations from the list to the right. Problem Statements Equations a. For the circuit shown, calculate the a CV equivalent capacitance? ANSWER: In(bla) b. When a circuit contain 4 resistors all connected such that the current flowing through R1 must flow through R2, then R3 and finally Re, we say these resistors are in series. Calculate the equivalent resistance. ANSWER: c. An RC circuit has one resistor of R 4500 and a single capacitor of C 300uf Calculate the time constant associated with charging/discharging the circuit. ANSWER: i, v d. The circuit below has a capacitor of 25uF, (15) initially uncharged. If the batter provides 12ov, after the switch S is closed how much charge passes through the circuit? ANSWER: RC (15) e. A parallel-plate capacitor has circular plates of 8.20 cm radius and 1.30mm separation. Calculate the capacitance. ANSWER:Explanation / Answer
