Here are some deep features of the solutions: Fundamentals Of Electric Circuits 7th Edition Solutions

• Given: $C = 10 \mu$F, $v = 10$ V
• Find: $i$, $q$
• Solution: $i = C \fracdvdt = 10 \times 10^-6 \times \frac101 = 10^-4$ A, $q = Cv = 10 \times 10^-6 \times 10 = 10^-4$ C

• Given: $V = 10 \angle 0^\circ$ V, $I = 5 \angle 30^\circ$ A
• Find: $P$, $Q$
• Solution: $P = VI \cos(\theta) = 10 \times 5 \cos(30^\circ) = 43.3$ W, $Q = VI \sin(\theta) = 10 \times 5 \sin(30^\circ) = 25$ VAR
