Electric Current (definition)
The net flow of charged particles
1 Coloumb =
The total charge supplied by a current of 1A in 1s
Current is the movement of
1) electrons in metals
2) ions in electrolysis
Conventional Current
positive to negative
Electrons flow
negative to positive
The net charge on a particle/object is …
quantised and a multiple of e (the elementary charge)
The resistance of an ammeter is
very small so that it doesn’t affect the circuit’s current
