An Inductance L and a Resistance R Are Connected in Series

question 17

Multiple Choice

An inductance L and a resistance R are connected in series to an ideal battery. A switch in the circuit is closed at time 0, at which time the current is zero. The rate of increase of the energy stored in the inductor is a maximum:

• A) just after the switch is closed
• B) at the time t = L/R after the switch is closed
• C) at the time t = 2L/R after the switch is closed
• D) at the time t = (L/R)ln 2 after the switch is closed
• E) a long time after the switch is closed

Definitions:

Identical Twins

Twins who develop from a single fertilized egg that splits into two, sharing 100% of their genes, and are thus genetically identical.

Twin Studies

Research studies that compare the similarity between monozygotic (identical) and dizygotic (fraternal) twins to assess genetic and environmental influences.

Adoption Studies

Research investigations that compare the traits and behaviors of adopted children to those of their biological and adoptive families, often used to understand the influence of genetics versus environment.

Heredity

The passing on of traits from parents to their offspring, either through asexual reproduction or sexual reproduction.
