-Format: Multiple-choice / Flashcard
Question 1: Parallel Circuit
Answer:
loads are placed between two supply wires, so that they all get the same voltage.
Question 2: Step up Transformer
Answer:
has more turns of wire on the output side which creates a stronger output voltage than input voltage.
Question 3: Electricity
Answer:
form of energy that can travel invisibly through conductors.
Question 4: Voltage Drop
Answer:
how much electrical pressure is used in a part of the circuit.
Question 5: Voltage
Answer:
force that affects the rate at which electricity flows through a conductor (aka: electrical pressure).
Question 6: Transformer
Answer:
essentially is two electromagnets placed next to each other.
Question 7: Load
Answer:
anything in a circuit, such as a heater, a light, or a motor, that uses power.
Question 8: Circuit
Answer:
loop of conductors that takes electricity from its source to the load and back to the source.
Question 9: Circuit Rule
Answer:
Current is the same at all points in a series circuit.
Question 10: Motor
Answer:
changes electric energy into kinetic energy.
Question 11: Direct Current (DC)
Answer:
steady flowing type of electricity, produced by batteries and used in flashlights, boom boxes, and computers.
Question 12: Step Down Transformer
Answer:
the exact opposite of a step up transformer.
Question 13: Semiconductor
Answer:
Can act as an insulator or a conductor.
Question 14: Circuit Breaker Box
Answer:
(1) Breaks up the load in a building into a number of circuits. (2) Prevents excess current from flowing into the circuits.
Question 15: Series Circuit
Answer:
All moving electrons pass through every part of the circuit, to include all loads and switches.
Question 16: Electric Power
Answer:
amount of power consumed by an electrical device.
Question 17: Ohms Law
Answer:
Describes the relationship between voltage, amperage, and Ohms: A = V/ ?.
Question 18: Frequency
Answer:
number of complete alternations from one direction to the other and then back again, that alternating current makes per second.
Question 19: Amperes
Answer:
represents current strength.
Question 20: Finding Resistance in a Circuit
Answer:
Series - add the resistance of each load; Parallel - add the inverses of the resistance.
Question 21: Generator
Answer:
changes kinetic energy into electric energy.
Question 22: Diodes
Answer:
Devices that allow a current to flow in one direction only.
Question 23: Insulator
Answer:
a material that resists the flow of electrons.
Question 24: Alternating Current (AC)
Answer:
type of current that changes direction many times per second.
Question 25: The Law of Electrical Power
Answer:
used to calculate the amount of power consumed by an electrical or electronic device: W= V x A.
Question 26: Electromagnet
Answer:
a current passing through a conductor creates a magnetic field around it.
Question 27: Ohms
Answer:
represents the measurement of the resistance in any circuit.
Question 28: Transistors
Answer:
Device that can switch a current, regulate its flow, or amplify a current.
Question 29: Electric Current
Answer:
the amount of electrons flowing through a conducting material.
