Capacitor |
|
|

Semi-conductor |
|
|
What are the two types of semi-conductors |
N-type and P-type |
|
|
A semi conductor whose charge is mostly (-) due to electrons being the charge carriers |
N-type |
|
|
A semi-conductor whose charge carriers are mostly holes (less electrons) |
P-type |
|
|
What is another name for potential difference or electric potential? |
EMF |
|
|
What is the phenomenom when a changing magnetic field creates a fluctuating electric field, and the fluctuating electric field creates a magnetic field? |
electromagnetism |
|
|
also called an electric field, it is a potential difference between two points (poles). |
electric lines of flux |
|
|
A pair of electrically fcharged poles |
electric dipole |
|
|
The rate at which charge carriers flow past a fixed point per unit of time is called |
Current |
|
|
Law showing relationship between voltage, current and resistance in DC and voltage, current and impedance in an AC circuit. |
OHMS LAW |
|
|
Both sine waves for voltage and current will have their positive alterations starting, peaking and returning to zero all synchronously. |
