Set 1 Section IV – Science
1. Electricity is a general term encompassing a variety of phenomena resulting from thepresence
and flow of electric charge. Which of the following statements about electricityis/are true?
a. Electrically charged matter is influenced by, and produces, electromagnetic fields.
b. Electric current is a movement or flow of electrically charged particles.
c. Electric potential is a fundamental interaction between the magnetic field and the presenceand
motion of an electric charge.
d. An influence produced by an electric charge on other charges in its vicinity is an electric field.
C
Electric potential is a fundamental interaction between the magnetic field and the presence andmotion of
an electric charge. Electric potential is the capacity of an electric field to do work on an electric charge,
typically measured in volts, while electromagnetism is a fundamental interaction between the magnetic
field and the presence and motion of an electric charge
2. Which of the following is/are not included in Ohm’s Law?
a. Ohm’s Law defines the relationships between (P) power, (E) voltage, (I) current, and (R)
resistance.
b. One ohm is the resistance value through which one volt will maintain a current of one
ampere.
c. Using Ohm’s Law, voltage is determined using V = IR, with I equaling current and R equaling
resistance.
d. An ohm (Ω) is a unit of electrical voltage.
D
An ohm (Ω) is a unit of electrical voltage is not true. Note: An ohm is a unit of electrical resistance.
3. The property of a conductor that restricts its internal flow of electrons is:
a. Friction
b. Power
c. Current
d. Resistance
