An Inductor of Inductance L and a Resistor of Resistance

question 34

Multiple Choice

An inductor of inductance L and a resistor of resistance R are connected in series.This series combination is then connected across the terminals of a battery.After a very long time,the battery is suddenly removed from the circuit and the circuit is made to form a closed loop so that the current continues to flow.How long after the battery is removed is the current flowing through the resistor equal to half its value before the battery was removed?

• A)t = L/2R
• B)t = L/R
• C)t = 2L/R
• D)None are correct.

Definitions:

Negative Reinforcer

A stimulus whose removal or avoidance following a behavior increases the likelihood of that behavior occurring again in the future.

Conditioned Stimulus

A formerly neutral signal that, once it is linked with an unconditioned stimulus, ultimately evokes a conditioned response.

Unconditioned Stimulus

In classical conditioning, a stimulus that naturally and automatically triggers a response without any prior learning.

Immediate Reinforcers

Immediate reinforcers are stimuli that follow a behavior and increase the likelihood of its repetition shortly thereafter.
