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.

We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
To supply the current needed to develop some horse power to turn over an engine.
power=i square*resistance or power=v suare/resistance
I suppose that the relation is directly proportional, because the more is the velocity, the more is the power wasted to keep the body moving, thus the resistance will be greater. JW70
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.
Mass measures the body's resistance to acceleration.
A hardcore, high intensity, total body fitness system created to develop an elite level of physical, mental and psychological conditioning using your body weight as the primary means of 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.
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.
Power=current squared times resistance
