How can you get power used from step down transformers

Click For Summary
SUMMARY

The discussion focuses on calculating the power usage in a household connected through two step-down transformers. The first transformer has a turns ratio of 1:29 and receives a primary current of 48 mA, resulting in a secondary current of 1.392 A. The second transformer, with a turns ratio of 1:32, delivers a voltage of 240 V to the house, leading to a calculated power usage of approximately 11,000 W. The calculations confirm that power input equals power output, adhering to the principle of conservation of energy in electrical systems.

PREREQUISITES
  • Understanding of transformer turns ratios
  • Knowledge of RMS (Root Mean Square) values in electrical systems
  • Familiarity with Ohm's Law and power calculations
  • Basic concepts of electrical circuits and current flow
NEXT STEPS
  • Study transformer efficiency and losses in electrical systems
  • Learn about advanced power calculation techniques in AC circuits
  • Explore the principles of electrical power distribution systems
  • Investigate the impact of load variations on transformer performance
USEFUL FOR

Electrical engineers, students studying power systems, and anyone interested in understanding transformer operations and household power consumption.

Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume that your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio=1:29) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 48 mA exists in the primary of this transformer. The secondary is connected to the primary of another step-down transformer (turns ratio=1:32) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.

Im lost :confused:

Hint: The voltage steps up as you move back towards the High voltage line, and power in equals power out.
 
I don't know if this is right...
but here's what i did
Is = IpNp/Ns
=48*10^-3 * 29 = 1.392A
Is = IpNp/Ns
=1.392A* 32 = 44.544A
P(avg) = Irms*Vrms = 44.544A * 240V = 1.1*10^4W

is this right?
