Zener Diode Circuit
A certain zener diode has a Vz=6.2V and a Zz=6.5ohms at a certain current. Sketch the equivalent circuit.?
it's just a perfect zener (or a 6.2 volt battery) in series with 6.5 ohm resistor.

Circuit - $8.99 A man hoping to move out of the closet falls into a trap of drug-fueled hedonism in this cautionary drama. John (Jonathan Wade Drahos) is a police officer from a small town who is forced to leave his career behind when it is discovered that he's gay. Hoping to find more tolerant surroundings, John moves to West Hollywood and rents an apartment with Nina (Kiersten Warren), an old friend from his high school days. One night, John attends a party where he meets Hector (Andre Khabazzi), an attractive hustler with whom he quickly strikes up a relationship. Hector is a regular on the L.A. party circuit, and John soon falls in with him, but the endless barrage of music, drugs, and anonymous sex proves more than John can handle, and he soon develops a dangerous dependence on amphetamines. William Katt, Nancy Allen, and Bruce Vilanch also appear in the supporting cast. Circuit had its premiere at the 2001 L.A. Outfest, a festival devoted to gay and lesbian-themed films. ~ Mark Deming, Rovi |

2 Zener Diode Basic
Circuit in alternating current?
Circuit in alternating current?
circuit in alternating current?
what it is the formula for a circuit to : the circuit is in alternating current
the first resistance is of 47 omhs, later has two to zener in series, one in opposite sense of the other and the voltage limitor resistance is of 33 omhs, . please i need the fornula
During the positive half-cycle, the diode of above leads and the one of down this in the zone to zener; therefore the exit is trimmed. The level will be the one of the tension to zener (diode in rupture) more 0' 7 v ((Diode with direct polarization). When this the negative half-cycle, happens on the contrary with which an almost square signal is obtained. Whichever greater it is the sinuidal wave of entrance, more perfect will be the square wave of exit
its polarization is always in inverse
sorry for my english!
Current =
volts-(Vz +0.7)
___________
Resistance
the problem is simple with DC
but with AC it's silly
if the AC peak voltage is less than the Zener voltage
no current flows
if it's greater then a part of a sinewave conducts
BUT if the zeners are connected to ground then they CLIP
and limit the voltage
peak current = (V peak - Vz ) / resistance
I excuse your English ...it just made the answer longer
because it was hard to understand fully
