In this procedure, you are given anesthesia so that you do not feel pain. The doctor then aggressively bends your knee in an attempt to break down the scar tissue. In most cases, this procedure is successful in improving range of motion. Sometimes, however, the knee remains stiff.
Resistance heating is a product of all circuits where electric current encounters resistance; although it has many beneficial uses, it can damage or destroy electrical equipment if not controlled. Anyone who has used a kettle, toaster, or a bar heater on a chilly evening has made the acquaintance of resistance heating.
Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Resistance is a measure of how much an object opposes the passage of electrons.The unit of electrical resistance is the ohm and it is represented by Ï. Every material has Resistance. Copper has a low resistance and wood has a high resistance.For example, a metre of copper has a resistance of only 1 Ohm but a metre of wood has a resistance of 10000000 ohm. We need resistance to reduce the flow of electrons through a circuit, so we can build resistors to behave as Electrical resistance.opper has a low resistance and wood has a high resistance.
