Physics 19: 1-4 EMF, Resistors, and Circuits


Reading Preparation

Text Reading: Giancoli, Physics - Principles with Applications, Chapter 19: Sections 1 to 4

Study Points

Key Equations

  • Resistance in a series circuit: R   =   R 1   + R 2   +   R 3   ...
  • Resistance in a parallel circuit: 1 R   =   1 R 1   +   1 R 2    +   1 R 3    ...

Web Lecture

Read the following weblecture before chat: DC Circuits

Study Activity


Use the lab simulation at Glencoe's Voltage, Current, and Resistance Lab to create circuits and vary current.

  • Follow the instructions to place a battery and light bulb (resistance) on the circuit and calculate the resulting current. Repeat your circuit construction and vary the batteries and light bulbs.
  • How can you maximize the current in your series circuit?
  • How can you minimize the current?
