|
Current (I) |
Directed movement of electrons in a conductor or circut from positive to negative |
|
|
Voltage (E) |
The difference of potential of two charges of interest |
|
|
Resistance (R) |
Opposition to current. Measured by Ohm (greek letter Omega) |
|
|
Hertz (Hz) |
Measurement of cycles you n a given period of time (frequency) |
|
|
Ohm's Law |
I=E/R Current in a circut is directly proportional to the voltage and inversely proportional to the resistance |
|
|
Alternating current |
Current which constantly changes in amplitude and reverses direction at regular intervals |
|
|
Direct current |
Current which stays at a constant amplitude and flows in only one direction |
|
|
