Electrical Quantities and Ohm’s Law:Delmar’s Standard Textbook of
Electricity 7th Edition
Define coulomb - correct answer ✔The charge transferred by a current of 1
amp in 1 second
Define Coulomb's law of electrostatic charges - correct answer ✔The force of
electrostatic attraction or repulsion is directly proportional to the product of the
two charges and inversely proportional to the square of the distance between
them
Define ampere - correct answer ✔Measurement of the amount of electricity
that is slowing through a circuit
An amp is equal to __ __ per second - correct answer ✔1 Coulomb
Define electron flow theory - correct answer ✔Because electrons are
negative particles, current flows from the most negative point in the circuit to
the most positive point
Define conventional current flow theory - correct answer ✔The current flows
from the most positive point to the most negative
Define current - correct answer ✔The flow of electrons through a conductive
substance
Define wavelength - correct answer ✔The distance that current travels
during one AC cycle
, A ___ must exist before current can flow through a circuit - correct answer
✔Complete path
A complete circuit is often referred to as a ___ - correct answer ✔Closed
circuit
If a switch is ___, there is no longer a closed loop and no current can flow -
correct answer ✔Opened
What occurs when the conductors leading from and back to the power source
become connected. A separate current path has been established that
bypasses the load. - correct answer ✔Short circuit
What occurs when a path other than the one intended is established to ground
- correct answer ✔Grounded circuit
A ____ provides the return path and completes the circuit back to the power
source - correct answer ✔Neutral conductor/ grounded conductor
Is the grounding conductor considered to be a circuit conductor? Why? -
correct answer ✔No because current will flow through the grounding
conductor only when a circuit fault develops. In normal operation, current
flows through the hot and neutral conductors only
The ___ is used to help prevent a shock hazard in the event that the
ungrounded, or HOT, conductor comes in contact with the case or frame of
the appliance - correct answer ✔Grounding conductor
