The device that converts electrical energy to mechanical energy is an electric motor. Electric motors are also used as generators in hybrid automobiles to convert mechanical energy back to electrical energy.
The name of device was material.
Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.
As the name suggest, a receiving device receives data that is transmitted by a sending device. Your wireless router and network access points are both senders and receivers. A receive-only device is one that receives but does not transmit. An RF receiver is an example of a receive-only device. E.g., a Freeview receiver can receive digital television transmissions but it does not transmit. A receiver is obviously not a computer in the traditional sense, but it does have microprocessors, memory and is re-programmable through firmware upgrades. It's primary purpose is to decode the transmissions it receives so, by any definition of the word, it is a computer.

well as the name mention production of magnetic field due to rotation. if we consider three identical coils axis physically by120* each and 3 phase supply given then their is the production of aleternating magentic field in each coil
A channel that displays programming as it is scheduled. In other words this channel does not require the device receiving the channel to be interactive. It is a term used for the opposite of on demand programming. The real question is why give it such a misleading name?
