Unit 2 9/18/ Notes
Question | Answer |
---|---|
What is electricity | Penomena associated with stationary and moving positive and negative charges |
What are the two types of electricity | Current and Static |
Electricity in motion | Current Electricity |
What kind of charges does current electricity have | Dynamic charges |
Electricity in rest | Static Electricity |
Triboelectricity | Static Electricity |
Study of stationary electric charges | Electrostatics |
The unit used to measure a static charge | Coulomb (C) |
Coulomb | Fixed (constant) number of positive or negative charges |
1C= | 63x10^18 charges or 6,300,000,000,000,000,000 |
Electrification | Process of applying a positive or negative charge to a neutral object through the transfer of electrons |
What must happen to make a neutral object become negative | Electrons must be added to the object |
What must happen to make a neutal object become positive | Electrons must be removed from the object |
What surrounds every charged object | Electrostatic field |
What is the charge of an electrostatic field surrounding a charged particle | The same as the charge on the object producing the field |
What is the area of an electrostatic field | The field area is determined by the intensity (quantity) of the chargeThe greater charge produces a larger field |
When is an object said to be grounded | When it is physically connected to the earth (ground) using material that will permit electrons to easily move between the earth and the object |
What is the primary goal of grounding throughout any facility | Safety(Personal and/or Equipment) |
An object that is positive has a deficiency of what | Electrons |
If a positive object is grounded where will the electrons move | From the earth to the positive object until the positive object is neutralized |
If a negative object is grounded where will the electrons move | From the object into the earth until the object is neutralized |
