An AC source operating at 60 Hz with a maximum voltage of 175 V is connected in series with a resistor (R = 2.0 k$\Omega$) and a capacitor (C = 2.5 $\mu$F). (a) What is the maximum value of the current in the circuit? .0773 A (b) What are the maximum values of the potential difference across the resistor and the capacitor? $\Delta V_{R, max}$ = 154.6 $\Delta V_{C, max}$ = 82 V V (c) When the current is zero, what are the magnitudes of the potential difference across the resistor, the capacitor, and the AC source? $\Delta V_R$ = 0 $\Delta V_C$ = 2.05 $\Delta V_{source}$ = 175 V X X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. V Your response differs from the correct answer by more than 100%. V How much charge is on the capacitor at this instant? 437.5 X Your response differs from the correct answer by more than 100%. $\mu$C (d) When the current is at a maximum, what are the magnitudes of the potential differences across the resistor, the capacitor, and the AC source? $\Delta V_R$ = 154.6 $\Delta V_C$ = 0 $\Delta V_{source}$ = 175 V V X Your response differs from the correct answer by more than 10%. Double check your calculations. V How much charge is on the capacitor at this instant? 0 $\mu$C

2) (F.2) Determine whether the following functions are injective, surjective, bijective, or neither. 1. a) $f: \mathbb{Z} \times \mathbb{Z} \to \mathbb{Z}$, where $f(x, y) = |x| + |y|$. 2. b) UCI is hosting an easter egg hunt in Aldrich Park! Each student who finds an easter egg gets to keep it. At the end of the event, every student in attendance found exactly one unique egg, but the student organizers ordered way too many easter eggs, so several undiscovered eggs are still lying around Aldrich Park. The function g maps a student to an easter egg. 3. c) The Python City Pizzeria has 96 seats in total. Currently, the restaurant is at half-capacity. Assume that each chair is occupied by at most one person. The function h maps each person to a chair in the restaurant.
