why resistance is in watts ??

[FMradio]

as far as i know about the basic electronics ,
The Unit of Resistance is ohms ok not watts
then y people used to say i want a resistance of 2 watts etc ???
then don't they say i need a resistance of _______ ohms ???

You probably didn't hear exactly. resistance is not in watts.
But resistors have (and need to have for obvious reasons) a power rating as additional parameter.

 

[hameeds01]

the unit of Resistence is Ω, & the unit of power is watt,
power of the resistor shows the maximum limit that it can Knob without burning.
p = v²/R

You may ask OK why we don't use a high power resistance if its power shows the maximum tolerable power of it.

the answer is that price and vlume is higher for higher power resistances.

You may ask OK why we don't use a high power resistance if its power shows the maximum tolerable power of it.

the answer is that price and volume is higher for higher power resistances.

If a big resistor is too expensive and is too big then re-design your circuit to use less power in the resistors.

Or use an IC without any resistors.
