Static Electricity The
The build up of charges on an object is called
static electricity
A conductor is a material through which a charge can flow easily.
An insulator .....
Does not allow charges to flow freely
Charges that are different, attract each other.
Charges that are the same,.....
repel each other
In a (blank) circuit, there is only one path for current to take
series
Protons have a (blank) charge
positive
What does it mean to "charge" an object
rubbing the object on another - usually an insulator
OR
moving electrons
A complete, unbroken path that charges flow through is called an.....
electric circuit
True or False:
An electric field gets stronger the closer it gets to an object
In a (blank) circuit, there are several paths for current to take; the different parts of the circuit are on separate branches
parallel
Neutrons have a (blank) charge
neutral
Charging by (blank) is the transfer of electrons from one uncharged object to another by RUBBING the objects together
friction
(blank) is the measure of how difficult it is for charges to flow through an object
resistance
Charges cannot be created or destroyed, but transferred is referred to as
the law of conservation of charge
Resistance is measured in...
Ohms
Electrons have a (blank) charge
negative
Charging an object by (blank) is the transfer of electrons from one object to another through DIRECT CONTACT
conduction
When electric charges are made to flow thorugh a material, they produce an....
electric current
True or False:
Most objects have some overall charge
False
There are multiple ways to present circuits from overheating in your home:
(blank) will melt if they get too hot
(blank) are switches that will bend away from circuits if they heat up
fuses
circuit breakers
Current is measured in....
Amps
Charging an object by (blank) is transferring with NO direct contact
induction
The difference in electric potential energy per charge between two points in a circuit is called (blank)
This is measured in volts
voltage
The loss of static electricity as electric charges transfer from one object to another is called
static discharge
Any circuit connected to the Earth via ground wires or a third prong on an outlet are considered....
grounded
An electric (blank) is a region around an object where the object's electric force is exerted on other charged objects
