Two 250-µF Capacitors and a 1

question 53

Multiple Choice

Two 250-µF capacitors and a 1.5-mH inductor are connected as shown in the figure. It is desired to "drive" the circuit by placing an ac generator in series with the inductor. Which one of the following generator output voltages will produce the largest current in the above circuit? Assume that V is in volts when t is in seconds.

• A)V = 0.6 sin[(1.1 × 10⁶ rad/s)t]
• B)V = 0.6 sin[(1.2 × 10³ rad/s)t]
• C)V = 1.2 sin[(5.3 × 10⁶ rad/s)t]
• D)V = 1.2 sin[(2.3 × 10⁵ rad/s)t]
• E)V = 2.8 sin[(4.6 × 10⁶ rad/s)t]

Anaerobic Respiration

A type of respiration that occurs without the presence of oxygen, using compounds other than oxygen to react with glucose to produce energy.

Aerobic Respiration

A metabolic process that uses oxygen to generate ATP by breaking down glucose and other nutrients; it occurs in the mitochondria.

ATP

Adenosine triphosphate, commonly referred to as ATP, is vital for transferring energy in cells to power metabolic functions.

Myoglobin

A red protein containing heme that carries and stores oxygen in muscle cells, very similar in structure to hemoglobin.
