Energy is the capacity to perform work. Power is the rate of work performed per unit time. Answer 5 P = IV Energy dissipated by an electrical resistance is usually manifest as heat, although sometimes it is also in the form of light. 8. Answer 6 A resistor with a high resistance rating (many ”ohms” of resistance) will dissipate more heat power than a lower-valued resistor, given the same. Power Power is the rate at which work is performed or energy is expended. W P= t The watt is the base unit of power. One watt is equal to 1 joule of work per second. Power is .

When a mass is attached to the end of the spring and allowed to come to rest, the vertical length of the spring is m. Calculate the elastic potential energy stored in the spring. The staples inside a. In Physics, power is associated with energy and has a precise meaning. The concept of power is concerned with how rapidly energy is being transferred or transformed when work is done. It is the rate of work done or rate of energy transfer. Power is measured in joules per second (J/s) r o watts (W) and is worked out using the formula:File Size: 1MB.
