Cables carry electrical power from the output of the transformer at a power station to the input of a second transformer at a substation. The power at the output of the transformer at the power station is $400\text{ MW}$. Which situation provides the greatest power to the input of the transformer at the substation?
- Apotential difference at power station transformer output: $200\text{ kV}$; diameter of cables: large
- Bpotential difference at power station transformer output: $200\text{ kV}$; diameter of cables: small
- Cpotential difference at power station transformer output: $400\text{ kV}$; diameter of cables: large
- Dpotential difference at power station transformer output: $400\text{ kV}$; diameter of cables: small
