Current in a resistor results in...
an electrical transfer of energy and a rise in temperature.
1 of 11
Watta (P)=
Amps (I) x Volts (V)
2 of 11
Energy trnaferred in Joules (E)=
current in amps (I) x potential differences in volts (V) x time in seconds (t)
3 of 11
AC and DC stands for...
alternating current and direct current.
4 of 11
DC flows in...
one direction.
5 of 11
AC current constantly...
changes direction.
6 of 11
If you put more lamps into a series circuit...
the lamps will be dimmer than before.
7 of 11
In a series circuit, if a lamp breaks or a componant is disconnected...
the circuit is broken and all the componants stop workng.
8 of 11
Series circuits are useful if...
you want a warning that one of the componants has broken or you need to use less wiring.
9 of 11
In a parralel circuit, if a lamp breaks or a componant is disconnected from one parrallel wire...
the componants on the other branches keep working.
10 of 11
If you add more lamps in parallel to a series circuit...
the lamps maintain te same brightness.
