- Homework Statement
- A transformer on a utility pole steps the rms down from 12kV to 240V. If the input current to the transformer is 2 A, what would the power loss have been if there were no transformer

- Relevant Equations
- ##I_S = \frac{N_P}{N_S}I_P##

##P_{loss} = I_S^2R##

##\frac{N_S}{N_P} = \frac{240}{12\times 10^3} = \frac{1}{50}##

##I_S = \frac{N_P}{N_S}I_P = \frac{N_P}{N_S}I_P = 50\times 2 = 100## Amps

##P_{loss} = I_S^2R##, but I don't know how to find R

##I_S = \frac{N_P}{N_S}I_P = \frac{N_P}{N_S}I_P = 50\times 2 = 100## Amps

##P_{loss} = I_S^2R##, but I don't know how to find R
