Question

To understand the units of inductance, the potential energy stored in an inductor and some of the consequences of having inductance in a circuit. After batteries, resistors, and capacitors, the most common elements in circuits are inductors. Inductors usually look like tightly wound coils of fine wire. Unlike As indicated by the equation in the introduction to this part, the current flowing through an inductor is related to the amount of electrical potential energy stored in the inductor. If the current is graphed as a function of time, the slope of the curve indicates the rate at which potential energy in the inductor is increasing or decreasing. The rate at which energy changes over time is known as power. Energy cannot be delivered to the inductor infinitely fast, nor can it be dissipated instantaneously in the form of heat or light by other circuit elements. Thus power can never be infinite. This implies that the curve of current versus time must be continuous. A graph is discontinuous when it contains a point at which the current jumps from one value to another without taking on all the values in between. When this happens, the slope of the curve at that location is infinite, which would imply infinite power in this case. Which of the graphs illustrate how the current through an inductor might possibly change over time? Type the numbers corresponding to the right answers in alphabetical order. Do not use commas. For instance, if you think that only graphs C and D are correct, type CD.

Explanation / Answer

The graphs (ABC) A, B and C indicates that the current changes over time.

All the circuits do not necessarily have indcutors in them, but every wire has a small amount of inductance, like an idial indoector a very small amount of resistance in the windings.
