answers rated A+
1. Coulomb's Force
2. Electric Field the space around a charged object in which another charged object
experiences an electric force
3. Voltage The potential difference; the amount of work to be done to move a charge
from one point to another along an electric circuit [J/c], [V].
4. Current Flow of positive charge [c/s], [A]
5. Power the rate at which work is done
6. Resistivity A material's opposition to the flow of electric current.
7. Resistance the opposition to the flow of electric charge [ohms]

8. Resistors in
Se- ries
9. Resistors in
Paral- lel
10. Current Divider
11. Variable Resis-
tors
Can be adjusted to change the resistance.
12. Photoresistor A light sensitive resistor; the more light that shines on it, the more it resists
so the less current there is
13. Thermistor A resistor that changes its resistance with a change of temperature.
14. Potentiometer A switch that can provide variable motion control. It can vary the resistance
within the switch, which attects both the current and voltage flowing out
of the switch.
