The whiteboard is attached to a wooden wall and the hand is holding a pen. On the whiteboard, there is a diagram of an AC load line, which is a type of electrical circuit. The diagram is written in black ink and appears to be a circuit diagram. 

There are several components of the circuit, including a transformer, a capacitor, and a voltage regulator. The transformer is connected to the capacitor and the voltage regulator, and there are several wires and cables connected to it. The capacitor is also connected to a voltage source, which can be seen in the diagram.

The diagram also includes a label that reads "AC Load Line" and a description of the components. The label also mentions that the circuit is labeled "Class A" and "Class B".</caption><caption><image_43>The image shows a person's hand holding a pen and writing on a whiteboard. The whiteboard is attached to a wooden wall and the person is writing on it with black marker. On the whiteboard, there is a diagram of an AC load line, which is a type of circuit that is used to control the flow of electricity in a circuit. The diagram consists of several components such as resistors, capacitors, transistors, and diodes. 

The diagram is labeled with the words "AC Load Line" and "Class A" at the top, indicating that it is a class A circuit. Below the diagram, there are two lines, one representing the current and the other representing the voltage. The lines are connected by arrows, indicating the direction of the current flow.

There is also a label on the left side of the image that reads "Class B" and a label that says "Class C". The label also mentions that the circuit is labeled as "AC load line".</caption><caption><image_44>The image is a photograph of a whiteboard with a hand pointing to a circuit diagram on it. The diagram is a circuit board with various components such as resistors, capacitors, transistors, and diodes. 

The circuit board is divided into two sections, with the left side of the board showing the circuit diagram and the right side showing the current and voltage levels. The current level is represented by a red line, while the voltage level is shown by a black line.

There are also several other components in the circuit board, including a capacitor, a resistor, and a capacitor. These components are connected by lines and arrows, indicating the direction of the current flow. The circuit board appears to be in a room with a wooden wall in the background.</caption></video><transcript><audio_45>to go through this point the reason being if you could imagine bringing the AC signal down to zero it would collapse onto the cue point so the AC resistance would have to be smaller than the DC</transcript><transcript><audio_46>resistance and therefore we would expect to see a greater slope a steeper slope for the AC load line in other words we might see something more along this line for our AC load line now there would</transcript> voltage V CEQ depending on where we bias this depending on the various resistors and power supplies and so forth all right it could be up here the cue point could be down here but we'll arbitrarily we'll just stick it right there so the question then becomes how is this modified in the AC case right what is the AC load line that's what we want to dive into here because that's going to tell us just how much of a AC signal swing we can get okay now as in the case of the DC load line the slope of this line is dictated by the DC resistance in the collector emitter the same thing is true in the AC case now right now we can say that the AC load line must share at least one point with the DC load line and that is the cue point it would have to go through this point the reason being if you could imagine bringing the AC signal down to zero it would collapse onto the cue point so the AC resistance would have to be smaller than the DC resistance and therefore we would expect to see a greater slope a steeper slope for the AC load line in other words we might see something more along this line for our AC load line now there would
