What can you do with a diode in a circuit?
So the first thing that you can do, and one of the ones that we don’t recommend is called the load line analysis. And that’s where you take the diode that you’re going to be using in the circuit and you physically take it into a lab, put a voltage across it and measure the current through it.
Is the diode circuit analysis an iterative thing?
So this is an iterative thing, where you have to go through and not only do you have to have all of those other things figured out, you then have to iterate and try and find exactly what that voltage drop is going to be over that. So it’s a pain and again, you probably don’t need it.
Which is the current through the diode and resistor?
And then you have your IS, which is the current through the diode and resistor. But you also notice on the right hand of the equation, there’s another VD, another voltage drops.
What’s the Q-point of a diode circuit?
But today we’re going to be solving circuits with diodes and then we’re going to be finding what the quiescent or Q-point is for those diodes and we’re going to be talking about the benefits of each of these methods. The Q-point is basically that point around which you don’t expect a whole lot of variation in the current or the voltage.
Can a diode be forward biased or reverse biased?
And this is where we just assume that if a diode is forward biased, there is no voltage drop across it. And if it’s reverse bias, then the voltage is whatever, it just happens to be in the circuit. So as we do this, there’s going to be four steps that we follow one when solving a circuit with the ideal diode model.
What should the voltage be in a series RC circuit?
Key Points In a series RC circuit connected to an AC voltage source, the currents in the resistor and capacitor are equal and in phase. In a series RC circuit connected to an AC voltage source, the total voltage should be equal to the sum of voltages on the resistor and capacitor.
