Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.
low, low |
|
high, low |
|
high, high |
|
low, high |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
A __________ electric current produces a magnetic field proportional to the amount of current flow.
moving |
|
low voltage |
|
high voltage |
|
stationary |
A moving electric current produces a magnetic field proportional to the amount of current flow. This magnetic field can be made stronger by winding the wire into a coil and further enhanced if done around an iron containing (ferrous) core.
