Chapter 46, Problem 1RQ
How is a zener diode connected in a circuit as compared to a common junction diode?
Expert Solution & Answer
To determine
The comparison between connection of Zener diode and common junction diode.
Explanation of Solution
Consider a diode, when the positive voltage is connected to anode and negative voltage to cathode, the diode is said to be forward biased. When the positive voltage is connected to cathode and negative voltage to anode, the diode is said to be reverse biased.
In general when a diode is broken, the region which the diode enters is Zener region which is considered to be as destroyed. The Zener diodes are specially designed for this operation and they are connected with reverse polarity applied to it.

- This problem studies the response of two single degree of freedom bridge systems shown in Figure 1 under three loading cases. The problem has two parts. Part A and Part B use the same loading cases but the system is modified. Assume the following three loading cases in both Part A and Part B: (a) Harmonic wind load acting on the bridge deck pw(t) = powsin(ωwt) with amplitude pow and forcing circular frequency ωw. (b) Harmonic displacement base excitation acting at the base of the bridge pier ug(t) = ugosin(ωgt) with amplitude ugo and displacement circular frequency ωg. (c) Rectangular pulse load acting on the bridge deck with amplitude pop and pulse duration td. Part A The system includes part of a bridge deck and a bridge pier shown in Figure 1(a). For each loading case find the symbolic expression of the peak shear force in the bridge pier assuming the following: • The bridge deck is rigid and it has a mass m. • The bridge deck is rigidly connected with the bridge pier (i.e.,…arrow_forwardspecific speed P #2 Q.2.
