The reason why Prometheus was punished was;
D. For stealing a spark from the heavens
Explanation:
Prometheus was punished by Zeus because Zeus vowed to revenge the act of Prometheus's stealing a spark of fire from Hephaestus, the god of fire, and metalworking and a son of Zeus and took it to humans whom Zeus had initially punished by holding back fire from humans so that humans will eat meat raw for being tricked by Prometheus into choosing the portion of the bull with bones while the animal flesh that was not chosen was given to humans.
DC motors are usually seen in applications where the motor speed needs to be externally controlled. AC motors work best in applications where power performance is sought for extended periods of time. All DC motors are single phase, but AC motors can be single phase or three phase.
AC and DC motors use the same principle of using an armature winding and magnetic field except with DC motors, the armature rotates while the magnetic field doesn’t rotate. In AC motors the armature does not rotate and the magnetic field continuously rotates.
In some applications today, DC electric motors are replaced by combining an AC electric motor with an electronic speed controller, known as variable frequency drives. DC electric motors are replaced with an AC electric motor and an electronic speed controller because it is a more economical and less expensive solution.
DC electric motors have many moving parts that are expensive to replace, and DC electric motor repair is usually more expensive than using a new AC electric motor with an electronic controller.
In our experience, combining an AC motor and drive proves to be the most cost effective solution for mostapplications. When servicing our customers in the field, we often recommend looking at the SMVector Series Variable Frequency Drive in combination with a three phase AC motor.
When capsaicin – the chemical in spicy foods that makes them so hot, Hot, HOT – hits your tongue, your body registers the sensation as pain. This in turn triggers the release of endorphins, otherwise known as “happy” chemicals that give you an instant head-to-toe feeling of pleasure.
