4 cards from this section. Quick, good the night before a test.
What is the primary function of a diode in a circuit?
Think about the directionality in circuits.
Define cut-in voltage.
What voltage must be exceeded for the diode to turn on?
What happens to the diode when the input voltage is below the cut-in voltage?
Recall the conditions for a diode to turn ON.
Are diodes characterized by linear I-V characteristics?
Think about how current changes with voltage in diodes.
You have a circuit with a silicon diode and a resistor where the input voltage is 5V. If the cut-in voltage is 0.7V and the resistor is 1k ohm, calculate the output voltage.
Use the concept of Ohm’s law for calculating the voltage drop across the resistor.
Design a basic rectifier circuit using a diode and explain how it converts AC to DC, including describing the output signal shape.
Visualize how diodes only allow positive voltages to pass through.
