1. What is the name of the natural magnet?
Soft iron
Lodestone
Magnesia
Alnico
2. Which of the following is the correct statement about coulomb?
One ampere per second
The amount of current of charge that flows past a point in one
second when the current is one ampere
An abbreviation for a certain combination of kilogram, meter and
second.
The quantity of charge that will exert a force of 1 N on a similar charge
at a distance of one meter.
3. If a light bulb in a series circuit burns out, what will happen to the other bulbs
in the circuit?
They will all go out.
They will remain lit.
Only the burned-out bulb will go out.
They will flicker before going out.
4. Describe how an electric generator utilizes magnetism in its operation.
, An electric generator relies on chemical reactions to produce
electricity.
An electric generator uses magnetism to store energy in batteries.
An electric generator transforms electrical energy into heat energy.
An electric generator converts mechanical energy into electrical
energy by using magnetism to induce electromotive force (EMF).
5. What is the equivalent term for electro-motive force (EMF)?
Resistance
Current
Power
Voltage
6. Describe how a series circuit differs from a parallel circuit.
A series circuit can have branches, while a parallel circuit cannot.
A series circuit has only one path for current to flow, while a parallel
circuit has multiple paths.
A series circuit is used in all household wiring, while a parallel circuit is
not.
A series circuit requires more voltage than a parallel circuit.
7. A short circuit:
Is perfectly normal
Is cool to watch
Generally causes undesirable current flow
Is more efficient than a 'closed' circuit
,8. What is the relationship between voltage and components in a parallel
circuit?
The voltage across each component is the same.
The voltage across each component varies.
The voltage is divided among the components.
The voltage is zero across all components.
9. How is a molecule formed?
molecule is formed by joining two or more atoms physically
. A molecule is formed by joining two atoms physically
. A molecule is formed by joining two atoms chemically
. A molecule is formed by joining two or more atoms chemically
10. Describe how a molecule is formed and the role of atoms in its structure.
A molecule is formed when two or more atoms bond together
through chemical bonds.
A molecule is formed by the fusion of electrons.
A molecule is created through electrical charge.
A molecule consists of only one type of atom.
11. What causes magnetism according to electrical science?
The presence of static electricity
The arrangement of atoms
The flow of thermal energy
The motion of electric charges
, 12. The definition of a series circuit is
a circuit that has only one path for current to flow
a circuit in which the applied voltage is the same at any point
(resistor) in the circuit
a circuit where the total resistance is less than the value of the lowest-
value resistor
a circuit in which the current is different at each point (resistor) in the
circuit
13. What are valence electrons and why are they important?
Valence electrons are electrons in the outermost shell of an atom
and they are important because they do not interact with other atoms
Valence electrons are electrons in the outermost shell of an atom
and they are important because they will interact with other atoms
Valence electrons are electrons in the innermost shell of an atom and
they are important because they will interact with other atoms
Valence electrons are electrons found in all atoms and that give an
element its chemical properties
14. What is an ampere?
Rate of electrical flow
opposition to electrical current
What happens when you drink an Amp energy drink
It indicates the rate at which electrons flow
