Exit Assessment 5 Electric
Current
Name
Date
The flow of charged particles (electric current) is
related to differences in potential energy.
◊ Each student will construct a simple circuit and
observe evidence of electric current.
1
A light bulb, wire and battery are arranged in several different set ups.
1. Which light bulbs will light? (you may select more than one)
A second light bulb is added in series to the closed circuit.
Use this diagram for questions 2-3.
2. What will happen to the brightness of the bulbs?
a) the brightness will increase
b) the brightness will decrease
c) the brightness will remain the same
3. What will happen to the current in the circuit when the second bulb is added?
a) the current will increase
b) the current will decrease
c) the current will remain the same
4. The number of electrons that pass a certain point in a conductor in a given amount of time is defined as
a) charge
b) electric current
c) potential difference
d) resistance
5. Which condition must exist between two points in a conductor in order to maintain a flow of charge?
a) a magnetic field
b) a potential difference
c) a high resistance
d) a low resistance
6. Why does the ball roll down hill?
a) The ball moves to decrease its potential energy
b) The ball moves to increase its potential energy
c) The ball moves to reduce gravitational force
d) The ball moves to increase gravitational force

Current
The flow of charged particles (electric current) is
related to differences in potential energy.
◊ Each student will construct a simple circuit and
observe evidence of electric current.
7. Why does the charge q move from plate A to plate B?
a) The charge moves to decrease its potential energy
b) The charge moves to increase its potential energy
c) The charge moves to reduce its momentum
d) The charge moves to increase its velocity
8. Why does the charge q move from plate A to plate B?
a) The charge moves to decrease its potential energy
b) The charge moves to increase its potential energy
c) The charge moves to reduce its momentum
d) The charge moves to increase its velocity
9. Why does the charge move through the light bulb?
a) The charge moves to decrease its potential energy
b) The charge moves to increase its potential energy
c) The charge moves to reduce its momentum
d) The charge moves to increase its velocity

The switch shown above is “open”.
10. Will the light bulb light? Explain your answer.
11. Examine this student statement.
Explain fully why you agree or disagree with the statement.
Support your answer with examples or experimental evidence.
“ Configurations C and E will light because there is a complete path from one end of the battery to the other. None of the others will light
because there is not a complete path . It is impossible to have the light bulb not light when there is a complete path from one end of the
battery to the other.”
12. What is meant by the term “closed circuit”? What is meant by the term “open circuit”? In which condition does charge flow through
the circuit?
