A.C. Generator
EMF can be increased by
increased number of turns on coil
increase area of coil
use stronger magnet
rotating coil faster
brushes are 2 contacts
rub against slip rings
connected to outside part of circuit
usually made of carbon
coil rotates
cuts magnetic field lines
EMF generated
makes current flow
coil is horizontal
current is maximum
field lines cut at fastest rate
coil vertical->no field lines
Currents
direct current(d.c)
electrons flow in singular direction
alternating current(a.c.)
direction of flow is reversed in regular time periods
coil is made of insulated copper wire
rotated by turning the shaft
coil travels upwards and downwards so current flows backwards and forwards
it is an alternating current
slip rings are fixed to coil and rotate with it
