Charging by Conduction and Induction Note: It is not necessary to copy all the details of all the examples

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

Charging by Contact – Conduction -negative object touched to a neutral object Before touching After touching neutral negative 5+ 2+ 5- 8- 0 6-

Charging by Contact – Conduction -negative object touched to a neutral object Before touching After touching neutral negative negative negative 5+ 2+ 5+ 2+ 5- 8- 8- 5- 0 6- 3- 3-

Charging by Contact – Conduction -positive object touched to a neutral object Before touching After touching positive neutral 5+ 2+ 3- 2- 2+ 0

Charging by Contact – Conduction -negative object touched to a neutral object Before touching After touching positive neutral positive positive 5+ 2+ 5+ 2+ 3- 2- 4- 1- 2+ 0 1+ 1+

Charging by Contact – Conduction Electroscope: a device used to detect static charge electroscope charging

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 Contact – Conduction Electroscope: a device used to detect static charge -charging with a negative object negative (4-) Before Contact neutral

Charging 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-)

Charging by Contact – Conduction Electroscope: a device used to detect static charge -charging with a positive object positive (4+) Before Contact neutral

Charging 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+)

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

Permanent charging by induction: Negative: 4. remove the ground and the object has a positive charge charging by induction tvo video
