A Thury system transmits how many amps at a maximum voltage of what value?

The Thury system, used in power transmission, is known for its ability to transmit high voltage and current efficiently over long distances. The correct response indicates that it can handle 150 amps at a maximum voltage of 27,000 volts. This combination is significant because it allows for a balance between the amount of current transmitted and the high voltage that minimizes losses due to resistance in the lines.

In a Thury system, maintaining higher voltages while transmitting current reduces the energy losses associated with heat in the conductors. The choice of 150 amps at 27,000 volts reflects a design that is optimized for effective long-distance transmission while ensuring that the infrastructure can support these parameters without excessive losses or safety issues.

The other options fail to align with the established specifications and operational limits of a Thury system. Specifically, they either exceed the safe or operational limits typically associated with this type of system or provide unrealistic combinations of current and voltage that wouldn't be feasible for reliable power transmission based on the technology available.
