Question

1. why was alternating current technology chosen as the standard for electrical power transmission?

alternating current won the competition because tesla was more aggressive with his opinions about edison and dc power.
it was decided by both tesla and edison that whoever won the war of the currents would choose the standard for electrical transmissions.
power companies had a better, more trusting relationship with tesla than they did with edison.
alternating current was found to be more efficient and is still used today in devices such as televisions and computers.

Explanation:

Alternating current (AC) is more efficient for long - distance power transmission. Transformers can easily change the voltage of AC. High - voltage AC transmission reduces power loss (using the formula \(P = I^{2}R\), where lower current \(I\) for the same power \(P\) reduces loss as resistance \(R\) is fixed for the transmission line). Also, AC can be easily converted to different voltages for various end - use applications. The other options are incorrect. Tesla's aggression (first option) is not a technical reason. There was no such pre - decided agreement between Tesla and Edison (second option). The relationship between power companies and Tesla (third option) is not the core technical and efficiency - based reason.

Answer:

Alternating current was found to be more efficient and is still used today in devices such as televisions and computers.
