electric current summary

Electrons flow from – to +

Conventional current flows from + to – i.e. flow of positive charge

d.c. direct current flows in one direction in a closed circuit, it is caused by a power supply

a.c. alternating current is when the current constantly reverses direction e.g. mains current alternates 100 times per second
Current is the same at every point in a series closed circuit cct

Sum of current flowing into a junction equals sum of current flowing out of junction

Ammeter is used to measure current and is always connected in series in the cct


Galvanometer is a sensitive ammeter/microammeter
