Name:_________________________ Lab Section:________ 4-digit Code Number:____________

  1. Draw the symbols for the following circuit elements: a battery, a light, a resistor, and a switch.
  2. Draw a circuit diagram for two resistors in parallel connected to a battery.
  3. In a second circuit digram add a light in series with the pair of resistors in the circuit above.
  4. Which bulb has the lower resistance: a 120-volt bulb that operates at 25 watts or a 120-volt bulb that operates at 500 watts?
  5. State Kirchhoff's loop rule for circuits. Explain in your own words what it means. How is it related to conservation of energy?
  6. State Kirchhoff's junction rule for circuits. Explain in your own words what it means. How is it related to conservation of charge?
