Current 3
|
- rate of flow of charge
- In metals = - charged electrons - conductors allow current to flow through |
|
|
Charge
|
Coulombs
|
|
|
Voltage 3
|
- Energy transferred per unit charge
- another name for potential difference -One volt is one joule per coulomb |
|
|
Resistance Definition
|
opposes the flow of current.
Bigger resistance smaller current |
|
|
Series Circuit
|
A1 = A2 = A3
V1 = V2 + V3 The current stays the same everywhere but voltage split |
|
|
Parallel Circuits
|
A1 = A2 + A3
V1 = V2 = V3 The voltage is the same anywhere but the current splits. |
