LC Circuits: a Charged Capacitor Is Connected to an Ideal

question 6

Multiple Choice

LC circuits: A charged capacitor is connected to an ideal inductor to form an LC circuit with a frequency of oscillation f = 1.6 Hz. At time t = 0 the capacitor is fully charged. At a given instant later the charge on the capacitor is measured to be 3.0 μC and the current in the circuit is equal to 75 μA. What is the maximum charge of the capacitor?

• A) 6.0 µC
• B) 10 µC
• C) 8.0 µC
• D) 2.0 µC
• E) 4.0 µC

Definitions:

Variable Costing

An accounting method that includes only variable costs (costs that change with production levels) in product costs and treats fixed costs as period expenses.

Unit Product Cost

The total cost incurred to produce, store, and sell one unit of a product, including material, labor, and overhead.

Absorption Costing

A bookkeeping strategy that includes the total manufacturing expenses - direct materials, direct labor, and all overhead costs, both variable and fixed - in determining the cost of a product.

Unit Product Cost

The total cost (including materials, labor, and overhead) divided by the number of units produced.
