Delmar's Standard Textbook of
Electricity Unit 2 (Electrical Quantities
and Ohm's Law)
What is a coulomb? - correct answer ✔A charge transferred by a current of 1
ampere in one second; a measure of charge.
What is an ampere? - correct answer ✔A unit of electric current equal to a
flow of one coulomb per second; current.
Define voltage. - correct answer ✔The potential difference between two
points in a circuit; electrical pressure.
Define ohm. - correct answer ✔The unit of resistance to current flow.
Define watt. - correct answer ✔The measure of the amount of power that is
being used in a circuit.
Would it be less expensive to operate an electrical unit on 120 V or 240 V? -
correct answer ✔It would cost the same since you are pushing the same
amount of wattage.
What letters can be used to represent amperes? - correct answer ✔I and A
What letters can be used to represent voltage? - correct answer ✔E and V
What letters can be used to represent an ohm? - correct answer ✔The
Greek letter omega or R
