Lesson objectives

By the end of the lesson, you will be able to:

• Describe the unit of resistance
• Apply Ohm’s law to determine current, voltage and resistance in an electrical circuit
• Describe how resistors in series affect current flowing in an electrical circuit
• Describe how resistors in parallel affect current flowing in an electrical circuit
• Explain how the length and diameter of a nichrome wire determine its resistance

The following practical and experimental skills will be developed:

• Observations
• Plotting
• Analysing
• Interpretation
• Reporting
