An LRC Ac Series Circuit with R = 15 Ω,L

question 32

Short Answer

An LRC ac series circuit with R = 15 Ω,L = 25 mH,and C = 30 μF,is attached to a 100-V (rms)ac power supply.The frequency of the power supply is adjusted so that the circuit is in resonance.
(a)What is the rms current in the circuit?
(b)What is the power dissipated by the circuit?

Definitions:

Short Run

A period in which at least one factor of production is fixed, limiting the immediate capacity to adjust to changes in demand.

Long Run

A time frame where every production factor and cost can change, providing complete flexibility to adapt to new situations.

Short-Run Supply

The supply of goods that exists when producers are able to change the quantity of the good produced in response to changing prices, typically within a limited time frame.

Curve

A graphical representation of the relationship between two or more variables in a coordinate system, often used in economics to illustrate supply and demand.
