ohms law question

[joelb79]

if you wire 2 reisitors in series, say 800m ohm and a 400m ohm, which one will get more power?

and if so, does the same apply to an ac ciruit?

Get more power? If you mean dissipate more power then:

The current flowing through both resistors will be the same so - power dissipated = current squared x resistance
V=IxR,    Power=VxI = (IxR)xI =I²R

thus the 400 ohm resistor will dissipate half the power of the 800 ohm resistor.

The result is the same for DC and AC.

Print this out and keep it handy.

well say instead of resistors, these are speakers.

in series, does a 4 ohm speaker get less power than an 8 ohm speaker? comon knowledge tells me that the 8 ohm speaker gets less power, but i may be wrong running ohms law into this formula.
