Connecting a Voltmeter to Series and Parallel Circuits: Understanding Internal Resistance

This lesson explores how to properly connect a voltmeter in both series and parallel circuits. Students will learn which configuration is appropriate for accurate voltage readings. We will also discuss the voltmeter's internal resistance and its importance for proper functioning. The learning objectives include applying Ohm's Law and the Power Law to solve circuit problems, practicing with series and parallel circuits, and preparing for an upcoming test on current electricity concepts. Review exercises will be provided to reinforce understanding.

Presentation Transcript

  1. Too Tau • Explain how you would connect a voltmeter to a circuit. Is this series or parallel? What does its internal resistance need to be in order to work properly.

  2. Objectives • Using our knowledge of Ohm’s Law and the Power Law, practice with Series Circuits ! • Now apply our physics understanding to solve parallel circuits for things like voltage, current and resistance.

  3. Homework: • Castle Learning – Review • TEST !! - Thursday (Friday if delay or snow day) - on all of Current Electricity (Packet)

  4. Finish Parallel Worksheet • Homework Review • Go through packet examples. • Resistance • Resistivity • Current • Ohm’s Law • Power Law • Series and Parallel Circuits • Then review questions.
