Electric Current
|
the controlled flow of charges
|
|
|
Discharge
|
to become neutral as with two parallel plate capacitors that are connected with a metal wire
|
|
|
charge carrier
|
The charges that move in a current. Charge carriers in metals are electrons. Insulators can not carry a current. Semiconductors can carry positive or negative charges, but not as easily as a conductor. In ionic solution charge carriers can be positive or negative

|
Potential and Electric field
|
wherever there is a potential difference, an electric field points from higher potential towards lower potential.
|
|
|
Electric Current and potential
|
It is the potential difference that creates a current. A Current can exist so long as there is a potential difference
|
|
|
Law of conservation of current
|
The current is the same at all points in a current-carrying wire
