Diode math problem
WebJan 9, 2024 · Solution : The first step is to determine the state of the zener diode. It is easy to see that for the given range of voltages (80 − 120 V), the voltage across the zener is greater than VZ (= 50 V). Hence the zener diode will be in the “on” state for this range of applied voltages. WebJan 9, 2024 · Since the diode current is negative, the diode must be OFF and the true value of diode current is ID =0 mA. Hence our initial assumption was wrong. In order to …

WebThere are two methods for solving/ analyzing the diode circuits. 1) Graphical Method 2) Diode Approximation Both methods have been discussed in the video and using the diode approximation method ... WebApr 29, 2024 · We know that we can't have current flowing this way and current flowing this way because there's nowhere else for the current to go in this node. The current goes here, current goes there, which means that this has to be less than zero volts so that the current can flow out that way. All right, update!
WebJan 9, 2024 · Since the collector diode is not forward biased, it is OFF and there can be neither collector current nor base current. Therefore, there will be no voltage drops across either resistor and the voltage at the base and at the collector leads of the transistor will be 12V. (ii) Open-base : Fig. 11 (ii) shows an open base failure in a transistor. WebApr 30, 2014 · I think the easiest method to solve such problems is to assume that the diodes are off (both, and then one of the two), compute the voltages across the diodes and see if there's a contradiction with your …
WebA diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance).It has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction … WebExample: Zener Diode Circuit Analysis Consider the circuit below: Note that the load resistor R L is in parallel with the Zener diode, so that the voltage V O across this load resistor is …
