Question

Define the break-away voltages of a circuit as the V coordinates on the circuit's operating curve in the i-V diagram where there are discontinuities in gradient. For example, the following i-V diagram indicates two break-away points, Voreak, at 2V and 2.5V. i (mA) 125 --- Segment Segment B Segment - - - - (V) 2.0 25 45 Such gradient discontinuities are typically caused by nonlinear devices such as diodes. Given the background information, answer the following questions. 0 + O + 0 + Ý A 10 10 10 (a) (b) (c) Consider the diagram above. Assume the voltage across the diodes including Zener diodes is 0.6V when the current is in forward direction. The reverse breakdown voltages for Zener diodes are given as V. for each plot. Please determine all the break-away voltage(s) for the circuits. a) Vbreak Enter as comma separated list b) The Zener diode's reverse breakdown voltage V = 5.1V. Vbreaks Enter as comma separated list c)The Zener diode's reverse breakdown voltage Vo = 5.1V. Vbreak Enter as comma separated list In the exam, be sure you can draw the i-V diagram for these circuits as demonstrated at the start of the question.
