Project #6738 - Physics

  • Two electrically charged particles held close to each other are released. As they move, the force on each particle increases. What can you say about the signs of the electric charge of each particle? Explain.


  • Are automobile headlights wired in parallel or in series? What is your evidence?


  • The voltage impressed across a circuit is held constant. If the resistance is halved, what change will occur in the current? How about if both voltage and resistance are doubled? (Refer to Ohm’s law)


  • Each of the two figures below shows an electric circuit with a voltage source and three resistances R1, R2, and R3. 

    1. Which of the three resistances carries the largest and smallest electric current in the circuit on the left?
    2. Which of the three resistances carries the largest and smallest electric current in the circuit on the right?
