Title: Charging by Conduction
1Charging by Conduction and Induction
Note It is not necessary to copy all the details
of all the examples
2Charging by Contact Conduction Charging by
Conduction charging an object by contact with a
charged object charging by contact
3Charging by Contact Conduction -negative
object touched to a neutral object Before
touching After touching neutral negative

object touched to a neutral object Before
touching After touching neutral negative

touching After touching positive

7Charging by Contact Conduction Electroscope a
device used to detect static charge electro
scope charging
8Charging by Contact Conduction Electroscope a
device used to detect static charge -any charge
added to the electroscope will spread out all
through it
9Charging by Contact Conduction Electroscope a
device used to detect static charge -any charge
added to the electroscope will spread out all
through it -any time the leaves get a charge,
they have the same charge so they repel
spread apart
10Charging by Contact Conduction Electroscope a
device used to detect static charge -charging
with a negative object negative
(4-) Before Contact neutral
11Charging by Contact Conduction Electroscope a
device used to detect static charge -charging
with a negative object negative
(1-) After Contact -leaves
repel due to like charges negative
(3-)
12Charging by Contact Conduction Electroscope a
device used to detect static charge -charging
with a positive object positive
(4) Before Contact neutral
13Charging by Contact Conduction Electroscope a
device used to detect static charge -charging
with a positive object positive
(1) After Contact -leaves
repel due to like charges positive (3)
14Charging by Induction
15Charging by Induction Charging by induction
charging a neutral object by bringing a charged
object close to, but not touching, the neutral
object.
16Charging by Induction Temporary charging by
induction Negative the negative charge will
drive the electrons of the neutral object away
17Charging by Induction Temporary charging by
induction Negative the negative charge will
drive the electrons of the neutral object
away remember protons don't move!
18Charging by Induction Temporary charging by
induction Negative the negative charge will
drive the electrons of the neutral object
away -creates a positive area close to the
charged object
19Charging by Induction Temporary charging by
induction Negative the negative charge will
drive the electrons of the neutral object
away -creates a positive area close to the
charged object -creates a negative area away
from the charged objects where the electrons
gather up.
20Charging by Induction Temporary charging by
induction Negative
21Charging by Induction Temporary charging by
induction Positive the positive object
attracts the electrons of the neutral object
22Charging by Induction Temporary charging by
induction Positive the positive object
attracts the electrons of the neutral
object -creates a negative area close to the
positive object where the electrons gather
23Charging by Induction Temporary charging by
induction Positive the positive object
attracts the electrons of the neutral
object -creates a negative area close to the
positive object where the electrons
gather -leaves the object positive on the side
away from the positive object
24Charging by Induction Temporary charging by
induction Positive
25Charging by Induction Permanent charging by
induction Negative 1. start with a neutral
object
26Charging by Induction Permanent charging by
induction Negative 2. bring a negative
charged object close so the electrons are
driven to the far side
27Charging by Induction Permanent charging by
induction Negative 3. ground the neutral
object so the electrons can leave
28Charging by Induction Permanent charging by
induction Negative 4. remove the ground and
the object has a positive charge charging
