Question 1.
What happens to a diode when the voltage exceeds the cut-in voltage?
Show hintHide hint
Think about the flow of current direction.
Question 2.
Define Thevenin's equivalent circuit.
Show hintHide hint
Consider how complex circuits can be simplified.
3Question 3.
What is the cut-in voltage of a silicon diode approximately?
- 0.3V
- 0.7V
- 1.0V
Show hintHide hint
Consider standard ranges of silicon diode components.
4Question 4.
When the diode is off, what is the expected current?
- True (current is 0)
- False (current is not 0)
Show hintHide hint
Think about the definition of 'off' for electrical components.
Question 5.
A diode circuit has a cut-in voltage of 0.7V and is connected in series with a 1kΩ resistor. How much output voltage will be across the resistor if the input voltage is 5V?
Show hintHide hint
Apply the diode voltage drop in your calculations.
Question 6.
If a circuit contains a capacitor of 10μF and is connected to Thevenin equivalent resistance of 1Ω, what will be the cutoff frequency of the resulting high-pass filter?
