144 W
Explanation:
The power absorbed by a resistor is the product of the current passing through it and the voltage drop across it. Hence


Other variations of this formula are derived using Ohm's law, 

is the resistance of the resistor. It is what causes the voltage drop.
Answer:

Explanation:
Each time the work done to raise a given mass is

here we know that


now we have


since it is just 25% of actual energy consumed as we know its efficiency is 25%
so we have total energy consumed in this way


now if it took N number of times so burn the fat of a pizza then


This is mr day and infact am seeing this… come into my office after class.
Well, let's take it the other way. If you have a rather low voltage (220 volts -- Europe -- is low) you'd get a high current, which more easily dissipates as heat, resulting in loss of energy. Using a high voltage you have a low current which could easily be transported with almost no loss.
