Explain the mechanism of formation of Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. 1. power: force: displacement: time: power and velocity. It is a subjective quality associated with a wave and is a bit more complex. Figure 1 shows a cyclist riding along a straight, level road at a constant speed. Inclined Plane in This means: Oscillations will build up and the amplitude will continuously riseuntil it will be limited - either it will be clipped (hard limitation) by the supply voltage or it will be (softly) limted by any non-linearity within the loop (decreasing gain for rising amplitudes). Convert figures to their SI values. [2] 2. The input characteristics of a transistor is obtained between the input current (I B) and input voltage (V B) when the output voltage V CE is constant.

The power equation shows that the overall power remains the same, P = V x I Power = Voltage x Current. Linear systems can be more complicated than an amplifier, however, and some are quite useful. In reality, the output power is always less than the input power because the changing magnetic field in the core creates currents (called eddy currents) which heat the core. It can also be described as the ratio of load to the effort applied. Answer: d i = 19.2 cm and Real. HAS NOT BEEN CALCULATED. Average Output. Search: Position Function Physics.
