for useful power 2output. In other words, — of the input goes into power loss. Accordingly, if the useful power output is to be 2 kilowatts, or2000 watts, the ratio of the power input to the useful power out-put is as follows: 10 ^ . , 10 10^10 10 Power mput = — =-X-=- 2000 ^ From which is obtained… … Fig. 35. Variation of Pressure duringOne Cycle circuits, the product of the pressure times the current in any circuitis always equal to the power, in watts, in the circuit. This, however,does not hold for a.c. circuits; so it cannot be said that the pressure that is applied to the terminalsof the…
