One joule represents (approximately): • The amount of electricity required to run a 1 W device for 1 s. • The energy required to accelerate a 1 kg mass at 1 m/s through a distance of 1 m. • The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s. WebThe equation used to calculate the power is: \ [power = \frac {work \\ done} {time \\ taken}\] \ [P = \frac {E} {t}\] This is when: power (P) is measured in watts (W) work done (E) is...
WebCurrent is the rate of flow of charge through a wire. Voltage is a measure of the energy of that charge. It is therefore possible to have two wires carrying the same current but one with much more energy than the other. The two circuits in Figure 2 explain this. The low voltage bulb has a current of 1 A flowing through it, it runs on 5 V and ...
