Lesson 2- Voltage and Current Flashcards
What is magnitude of charge? How does it relate to electrons and protons?
They both have the same magnitude (amt) of charge.
What is the symbol of magnitude charge for protons?
e
What is the symbol for magnitude charge for electrons?
-e
What unit is for positive charge?
1 coulomb
What unit is use for negative charge?
-1 coulomb
voltage
measure of potential energy
potential energy
amount of energy stored in an object
kinetic energy
energy in motion
What is voltage relative to?
a pre defined ground level; ex. more or less negative charge
formula for volt
one joule per coulomb of charge
joule
unit of energy
volt
measure of how much potential energy a charged object has at any particular location relative to ground
current
the amount of charge (coulombs) that passes through a wire
What is the unit of current?
ampere
Define ampere
flow of one coulomb per second
