Charging by Contact – Conduction
Charging by Conduction: charging an object by contact with a charged object

Charging by Contact – Conduction
Electroscope: a device used to detect static charge
-any charge added to the electroscope will spread out all through it
Charging 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

Charging by Induction
Charging by Induction
Charging by induction: charging a neutral object by bringing a charged object close to, but not touching, the neutral object.
Charging by Induction
Temporary charging by induction: Negative: the negative charge will drive
the electrons of the neutral object away
Charging by Induction
Temporary charging by induction: Negative: the negative charge will drive
the electrons of the neutral object away
*remember: protons don't move!
Charging 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
Charging 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.
Charging by Induction
Temporary charging by induction: Negative:
Charging by Induction
Temporary charging by induction: Positive: the positive object attracts the
electrons of the neutral object
Charging 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
Charging 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
Charging by Induction
Temporary charging by induction: Positive:
Charging by Induction
Permanent charging by induction: Negative:
1. start with a neutral object
Charging by Induction
Permanent charging by induction: Negative:
2. bring a negative charged object close so the electrons are driven to the far
side
Charging by Induction
Permanent charging by induction: Negative:
3. ground the neutral object so the electrons can leave
Charging by Induction
Permanent charging by induction: Negative:
4. remove the ground and the object has a positive charge
