In this lesson, we will learn how to describe how electrical resistors work and how adding resistors can change the overall resistance in series and parallel circuits.

Students will be able to

Q1:

Does this circuit diagram represent a series circuit or a parallel circuit?

Q2:

In a circuit diagram, we use symbols to show how electrical components are arranged in the circuit.

The symbol \n\r represents the wire.

Which of these symbols represents a resistor?

What does the following symbol represent?

Q3:

Which component of this circuit is a resistor?
