In terms of attraction and repulsion, how do negative particles

1. What condition is necessary for the sustained flow of water in a pipe? What analogous

condition is necessary for the sustained flow of charge in a wire?

2. What is an ampere?

3. Why is a current-carrying wire normally not electrically charged?

4. Does charge flow through a circuit or into a circuit? Does voltage flow through a

circuit, or is voltage established across a circuit?

5. Will water flow more easily through a wide pipe or a narrow pipe? Will current flow

more easily through a thick wire or a thin wire?

6. Does heating a metal wire increase or decrease its electrical resistance? 7. If the voltage impressed across a circuit is held constant while the resistance

increases, what change occurs in the current?

8. If the resistance of a circuit remains constant while the voltage across the circuit

decreases, what change occurs in the current?

9. What is the error in saying that electrons in a common battery driven circuit travel at

10. What is the error in saying the source of electrons in a circuit is the battery or

generator?

11. What is an electric circuit?

12. How much current flows in a 1000 ohm resistor when 1.5 volts are impressed across it? 13. If the filament in an automobile headlamp is 3 ohms, how many amperes does it draw

when connected to a 12 volt battery?

14. How much resistance allows an impressed voltage of 6 V to produce a current of 2 A 15. What is the voltage across a 100 ohm circuit that draws a current of 2 amperes? 16. What is the power when 120 V drives a 2 ampere current through a CD player? 17. What is the current in a typical 60 watt light bulb which is plugged into a 120 V socket? 18. If part of a circuit dissipates energy at a rate of 6 watts when it draws a current of 3

amperes, what voltage is impressed across it?
