We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
power=i square*resistance or power=v suare/resistance
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
Power=current squared times resistance
I never measured the resistance of an electric iron, but: the 15 ohm resistance is probably required to develop a required 806 watts of power. Using Ohm's law, I(current) = E(voltage)/R(resistance), therefore I(current) =110 volts/15 ohms = 7.33 Amps (current), and, Power (watts) = E(voltage) X I(current); 110 volts X 7.33 amps = 806 watts. The iron requires that wattage to develop enough heat in the sole of the iron. Hope this helps.

Physical resistance is force applied against another force or inanimate object. So for example, doing push-ups is a physical resistance exercise. Leaning on your hands, placed against a wall, while standing up and bringing your body to your hands is a form of resistance exercise. Or using 'therabands' or weights creates resistance. Remember to start off slowly, with low weights or low reps, so you don't injure muscles, ligaments, or tendons.
To supply the current needed to develop some horse power to turn over an engine.
The velocity of a moving body is inversely proportional to the resistance it faces. This means that as the resistance increases, the velocity of the body decreases, and vice versa. More resistance leads to slower movement, while less resistance allows for faster movement.

Satyagraha, or passive resistance, was developed and expanded on by Gandhi as an alternative to the type of passive resistance discussed by Thoreau in â??On Civil Disobedienceâ??. He believed his version stressed love and a lifestyle that incorporated mind, body and spirit.
The power vs resistance graph illustrates how power output changes with varying levels of resistance in a system. It can be used to analyze the relationship between power and resistance by showing how power increases as resistance decreases, and vice versa. This graph helps in understanding how changes in resistance impact the power output of a system.
