Test Description: Study these concepts so you can pass Derith's final exam.
Instructions: Answer all questions to get your test result.
1) Which of the following statements is true?
A
Negative charges are attracted to negative charges.
B
North poles attract north poles.
C
Positive charges attract positive charges.
D
South poles are attracted to north poles.
2) Why might there be an adapter on a power cord?
A
To change the voltage and convert DC to AC
B
To change the voltage and convert AC to DC
C
To make the current alternate more frequently
D
To make the current alternate more frequently and change the voltage
3) What will happen to a neutrally charged, light metal sphere placed very near the Van de Graf?
A
It will be attracted and then repelled.
B
It will be repelled and then attracted.
C
It will always be repelled.
D
It will always be attracted.
4) What actually moves in a DC circuit?
A
Protons from the positive terminal to the negative one.
B
Protons from the negative terminal to the positive one.
C
Electrons from the positive terminal to the negative one.
D
Electrons from the negative terminal to the positive one.
5) In fluorescent tubes, how is the electricity changed into light?
A
Electricity causes the molecules inside the tube to vibrate releasing the energy as light as their vibrations dampen.
B
The white coating on the inside heats up due to the electric current and then gives off photons as a result.
C
Electrons in the gas are sent to higher energy levels and then release light as they fall back to the lower levels.
D
Electricity causes the chemicals inside the tube to break chemical bonds releasing the light as the molecules break down.
6) A circuit has one resistor and one battery. Which of the following will NOT decrease the current flow?

All of these answers will decrease the current.
D
Connecting another resistor in parallel with the first
7) How can I increase the repulsive force between two charges?
A
Decrease the charge of the first
B
Move them farther apart
C
Change the material from which they are made (without changing the charges)
D
Increase the charge of the second
8) Which of the following occurs in induction?
A
Like charges are attracted.
B
The originally charged object is attracted to the originally neutrally charged object.
C
Unlike charges are repelled.
D
The objects repel one another.
9) What is the process by which a neutrally charged conductor can become electrically attracted to a charged object called?
A
Polarization
B
Quantum Chromodynamics
C
Combustion
D
Sonoluminescence

B
The neutron and the electron have equal and opposite charges.
C
The proton and the positron (anti-electron) have the same charge.
D
Up and down quarks have equal and opposite charges.
11) When connecting a voltmeter and an ammeter in a circuit, which of the following describes how they should be connected to give proper readings?
A
Both should be connected in series.
B
The voltmeter should be in series, by the ammeter should be in parallel.
C
The voltmeter should be in parallel, but the ammeter should be in series.
D
Both should be connected in parallel.
