Electricity Flashcards
Static Electricity
Current Electricity
Not moving electricity
Moving electricity through appliances
How to be positivity or negativity charged
Positive charges (sweeping off negative charge) and negative charges (bring electrons onto you)
Electricity
Built up charge either positive or negative
What do positive and negative do
And what do two of the same charges do
1) attract
2) repel
What’s magnitude of force vs just the force
1) asking for just the number
2) asking for number and if it’s attracting or repelling
Gravity is always ….
So I were to draw it where would the arrows go
1) attract
2) pointing towards the object
How do I draw field lines for positive
And for negative
1) away
2) inward
If Mr.Morochnik gives the charge as 5C what do I have to do?
What if it was 5q
1) keep it as 5c because that’s the unit for electrical charge
2) then you would have to multiply it by the electron charge
Electro Static Force
Force that exists btwn two charged electrons/objects
Electric Field
Field that represents how strong it would be at a given location
Voltage also known as
Potential Difference
What’s potential difference
Measure of how much energy is transferred btwn two points in a circuit
Voltage/potential diff units
v
V = (formula)
W/Q = Fd/q = ED
Current formula
I (current) = q/t
Q = amt of charge
T = seconds
