How do you find your V0?
To find the voltage at Vo, start at either end and add or subtract the voltage drop across the resistor.
- If we start at the 10V end: Vo = 10 – 3.58 = 6.42 V.
- If we start at the -2V end: Vo = -2 + 8.42 = 6.42 V.

How is Zener calculated?
How to Calculate Zener Diodes
- Determine the maximum and minimum load current (Li), for example 10 mA and 0 mA.
- Determine the maximum supply voltage that may develop, for example a 12 V level, also ensuring that the minimum supply voltage is always = 1.5 V + Vz (the zener voltage rating).
How is Zener resistor calculated?
- The zener resistance can be calculated…
- By the following process:
- Zener diode ZD is used to generate a regulated DC output.
- R = Vin – Vz / Iz.
- Where Vin is the input voltage, Vz output voltage and Iz current through the Zener In most circuits, Iz is kept as low as 5mA.
- So the value of R3 appears as.
What is v0 and V?
velocity is v0. At a later time t the position is x and the velocity v. The acceleration a is constant. during all times.
Why does the voltage of a Zener diode match the voltage at Vout?
If the voltage at the output was higher than Vz, the diode would have low resistance and short out the output, which means that the voltage would drop (because of the resistor in series). So, the circuit reaches an equilibrium of Vout=Vz.
Which is the current limiting resistor, VIN or vz?
When Vin>Vz, and there is a current flowing through the zener, the voltage drop of the zener will be always Vz. The voltage drop of the current-limiting resistor will always be Vin – Vz, which in your circuit will be always 9V – 5V = 4V.
Why is the resistor Rs selected in a Zener diode?
Resistor RS is selected so to limit the maximum current flowing in the circuit. With no load connected to the circuit, the load current will be zero, ( IL = 0 ), and all the circuit current passes through the zener diode which in turn dissipates its maximum power.
Why does a Zener have to conduct less current?
Secondly, as the load draws more current, the zener has to conduct less current, because the current through the resistor (which determines the output voltage) is the sum of the zener current and the load current. At some point, the load draws enough current on its own such that the zener doesn’t have to conduct any.
