LR Circuits - Review for AP Physics C: Electricity and Magnetism

The video tutorial reviews LR circuits in AP Physics C, focusing on the behavior of circuits with inductors and resistors. It explains the initial and steady-state conditions of current, applies Kirchoff's Loop Rule, and derives equations for current as a function of time. The concept of time constant is introduced, and the tutorial draws an analogy between LR circuits and motion with drag force. The session concludes with a preview of LC circuits.

Discuss the relationship between the time rate of change of current and the maximum current in an LR circuit.

What is the significance of the 63.2% change in current in relation to the time constant?

What are the implications of the analogy between current in a circuit and velocity of a moving object?

How can the behavior of an LR circuit be compared to the motion of an object under the influence of gravity?
