Answer

NO, IT IS NOT....
oms law is " as physical state of conductor remains same
the voltage applied is directly propertional to current
flowing through it."

but in case of semiconductor current flowing through it
depends on many factors as its breakdown voltage,its
polarity,its forbidden energy gap,etc

Question { 24678 }

why rating of motor in HP?


Answer

HP is non-SI units of power,
1 HP = 746 Watts.OR 1HP x 0.746 = kW

It was originally defined to allow the output of steam
engines to be measured and compared with the power output
of draft horses.
Practicaly all system measurements converts into Electrical
System for simplicity and easy valuable results
