5.1.1. Introduction

Try these first

1. 1.

   Define a non-linear circuit in your own words.

   Hint

   Think about components that have varying relationships.

2. 2.

   What is a diode?

   Hint

   Consider how it behaves in a circuit.

3. 3.

   What is KCL?

   • Koalas Create Lollipops
   • Kilowatt Consumed Load
   • Kirchhoff's Current Law

   Hint

   Remember the flow of current at junctions.

4. 4.

   True or False: Kirchhoff's Voltage Law states that the total voltage around a closed circuit is zero.

   • True
   • False

   Hint

   Think about energy conservation in a circuit.

5. 5.

   Given a circuit with a diode in series with a resistor connected to a 5V source, where the diode's forward voltage drop is 0.7V, determine the current flowing through the circuit if the resistor is 1kΩ.

   Hint

   What is the voltage across the resistor?

6. 6.

   How do the characteristics of a diode affect the overall behavior of the circuit containing resistors in series and parallel? Illustrate with a circuit diagram.

   Hint

   Consider how current divides in a parallel circuit versus a series circuit.
